Question

Compute the average number of heads from the ten trials (add up the number of heads and divide it by 10).
Change this to the average probability of tossing heads by putting the average number of heads in a fraction over the number of coins you used in your tosses.
Did anything surprising or unexpected happen in your results for this experiment?
Write the sample space for the outcomes of tossing three coins using H for heads and T for tails.
What is the probability for each of the outcomes?
Which kind of probability are we using here?
How come we do not need to have three actual coins to

Answer 1

See where i got stuck

Answer 2

not really. i did a project jut like this except on genetics. where did u get stuck??

Answer 4

sorry about the numbers im a little tired but i have to get this in

Answer 5

i understand. i shall do my best to help you.

Answer 6

thank you

Answer 7

your welcome. so how many H and T did u get total?

Answer 8

there is my discussion to give the main idea of where i am

Answer 9

it wont let me c it

Answer 10

In your own words, describe two main differences between classical and empirical probabilities.
The difference between classical and empirical. The classical probability also assumes all the outcomes which are favorable to the reoccurrence.
Empirical is based on the observed by frequencies.
Gather coins you find around your home or in your pocket or purse. You will need an even number of coins (any denomination) between 16 and 30. You do not need more than that. Put all of the coins in a small bag or container big enough to allow the coins to be shaken around. Shake the bag well and empty the coins onto a table. Tally up how many heads and tails are showing. Do ten repetitions of this experiment, and record your findings every time.
Shake Heads Tails
1 6 10
2 8 8
3 9 7
4 9 7
5 6 10
6 7 9
7 8 7
8 9 7
9 7 9
10 12 4

 
I used 16 coins
The formula that I used was P (E) Observed Frequency of Specific event (f) = f
Sum of Frequency n
In my first count the probability of tossing a head was:
6/16=3/8
In my first count the probability of tossing a tail was:
10/16=5/8

Answer 12

thats the tails

Answer 13

for tails its 7.8

Answer 14

they are asking for just the heads

Answer 15

head is 8.1

Answer 16

is that the average

Answer 17

thats it added and divided im working on the average. so that i feel like im helping u and not jut giving u the answer what did u learn about average? any specific things?

Answer 18

i hate to be a pain but i have to see the work cause i have to show my work even on a discussion

Answer 19

what did u learn about averages? i'll how u the work. and sorry if im a little slow at helping but im in the middle of an exam and a 90 point assignment.

Answer 20

show*

Answer 21

we just started the average so this is my first turn around it

Answer 22

you haven't learned anything about it?

Answer 23

nope

Answer 24

to find an average you add all your numbers together and then divide it by the amount of numbers you added.

i did do your T for example.

10 + 8 + 7 + 7 + 10 + 9 + 7 + 7 + 9 + 4 = 78

now you count how many number you added together(which is ten)

78 ÷ 10 = 7.8

Therefore your average of T - 7.8

is that easier to understand?

Answer 25

So what i need to do is add all my heads #'s toger

Answer 26

after doing that i get 78

Answer 27

7.8 after dividing it

Answer 28

the H average is 8.1

6 + 8 + 9 + 9 + 6 + 7 + 8 + 9 + 7 + 12 = 81

divide 81 by the number of numbers you added together(which is ten)

81 ÷ 10 = 8.1

Therefore your average for H i 8.1

Answer 29

yes. you got it! (: did i help you to better understand this?

Answer 30

yes
but here is the instuctors example

Answer 31

6 of my repetitions came out to have exactly the same number of heads and tails
This did not happen every time because the outcomes occur and random.
I am using empirical probability
The average number of heads came out to be 11.8%
10+14+14+11+13+5+10+13+17+11=118/10= 11.8%

The average probability of getting heads is 59%
11.8/20=59%

I turned out that 59% of the time, the coin fell on heads. I thought that was very interesting because I expected it to be more equal,
The sample space for the outcomes of 3 coins are:
· HHH, TTT, HHT, TTH, HTH, THT, THH, HTT
1
8

· We are using the classical probability

Answer 32

now you see why im a little confused

Answer 33

so you need percentages?

Answer 34

yup

Answer 35

easy

Answer 36

remember what I just taught you?

Answer 37

ok

Answer 38

you are going to have to bare with me im also sick with the flu

Answer 39

take each average average. let do 7.8 so i dont confuse you

7.8 ÷ 20 = 39%

8.1

8.1 ÷ 20 = 405%

Answer 40

i know it doesnt look right. but it is. all you do is tak your average and divide that by 20.

Answer 41

no way! mee too!!! i had high fever all day yesterday! and its fine! i know how it is trying to do things that you dont understand in a deadline im jut glad i could help you(:

Answer 42

can you show me where i am supose to put the numbers

Answer 43

i have over 102 for the past 4 days and my vision is blurry

Answer 44

i had 103 yesterday and was throwing up all day. and put what numbers where?

Answer 45

6 of my repetitions came out to have exactly the same number of heads and tails
This did not happen every time because the outcomes occur and random.
I am using empirical probability
The average number of heads came out to be 11.8% was my next step

Answer 46

the bad thing is i have 12 different kinds of seziures

Answer 47

oh im sorry :( i hope u get better soon! and i dont understand the above :/ what are you talking about?

Answer 48

In your own words, describe two main differences between classical and empirical probabilities.
Gather coins you find around your home or in your pocket or purse. You will need an even number of coins (any denomination) between 16 and 30. You do not need more than that. Put all of the coins in a small bag or container big enough to allow the coins to be shaken around. Shake the bag well and empty the coins onto a table. Tally up how many heads and tails are showing. Do ten repetitions of this experiment, and record your findings every time.
State how many coins you have and present your data in a table or chart.
Consider just your first count of the tossed coins. What is the observed probability of tossing a head? Of tossing a tail? Show the formula you used and reduce the answer to lowest terms.
Did any of your ten repetitions come out to have exactly the same number of heads and tails? How many times did this happen?
How come the answers to the step above are not exactly ½ and ½?
What kind of probability are you using in this “bag of coins” experiment?
Compute the average number of heads from the ten trials (add up the number of heads and divide it by 10).
Change this to the average probability of tossing heads by putting the average number of heads in a fraction over the number of coins you used in your tosses.
Did anything surprising or unexpected happen in your results for this experiment?
Write the sample space for the outcomes of tossing three coins using H for heads and T for tails.
What is the probability for each of the outcomes?
Which kind of probability are we using here?
How come we do not need to have three actual coins to compute the probabilities for these outcomes?
Respond to at least two of your classmates’ postings. Make sure you review their data and calculations and let them know if their probabilities seem accurate.

Answer 49

that is the instuctions on how she wants it to be placed

Answer 50

Change this to the average probability of tossing heads by putting the average number of heads in a fraction over the number of coins you used in your tosses.

how many coins did u use?

Answer 51

16

Answer 52

The sample space for the outcomes of 3 coins are:
· HHH, TTT, HHT, TTH, HTH, THT, THH, HTT
1
8

· We are using the classical probability

here she is saying all the possible outcomes

Answer 53

In my first count the probability of tossing a head was:
6/16=3/8

Answer 54

ok. can u simplify that fraction anymore?

Answer 55

3/8

Answer 56

can u simplify 3/8 any further?

Answer 57

no

Answer 58

then that i your final answer

Answer 59

In my first count the probability of tossing a tail was:
10/16=5/8

Answer 60

no 5/8 w as i can go

Answer 61

i got confused after that

Answer 62

5/8 is your final answer. is cant be simplified anymore

Answer 63

it is the steps after that i get confused

Answer 64

no more steps. that the final fraction
