Question

I NEED HELP ILL FAN AND MEDAL YOU PLEAASSEEE!!!! I ONLY NEED 1.3.5

Answer 1

post your question please

Answer 2

Flip two coins 100 times, and record the results of each coin toss in a table like the one below:
Result Frequency
Two heads
Two tails
One head, One tail
Answer the following questions based on the data you gathered. You must show your work to receive credit.
1. What is the theoretical probability that a coin toss results in two heads showing?

2. What is the experimental probability that a coin toss results in two heads showing?

3. What is the theoretical probability that a coin toss results in two tails showing?

4. What is the experimental probability that a coin toss results in two tails showing?

5. What is the theoretical probability that a coin toss results in one head and one tail showing?

6. What is the experimental probability that a coin toss results in one head and one tail showing?

7. Compare the theoretical probabilities to your experimental probabilities. Why might there be a difference?

Answer 3

@Vocaloid

Answer 4

start by flipping the coins and filling in the table

Answer 5

I did two heads are 28 and two tails are 31 and one head and one tail is 41

Answer 6

@Vocaloid

Answer 7

ok, let's start with the first question

Answer 8

1. theoretical probability of two heads = number of 2-heads/total number of flips = ?

Answer 9

what ? im confused

Answer 10

how many times did you get 2-heads?

Answer 11

28

Answer 12

good, so

2-heads/total number of flips = ?

Answer 13

28

Answer 14

100

Answer 15

/ means divide

Answer 16

.28

Answer 17

right, small mistake on my part, this should be the answer for 2, not 1

Answer 18

to answer the question for 1, all we need to do is multiply

(probability of heads)*(probability of heads)

where the probability of heads is 1/2

Answer 19

okay that's it?

Answer 20

3?

Answer 21

@Vocaloid

Answer 22

for two tails, multiply

(probability of tails)*probability of tails

Answer 23

.31 last one is .41 @Vocaloid

Answer 24

nope

Answer 25

for theoretical probability we ignore the data

Answer 26

what's the probability of getting a tails? (don't look at your data, just consider a coin by itself)

Answer 27

1/2 @Vocaloid

Answer 28

good, so what is (probability of tails)*(probability of tails)?

Answer 29

2/4?

Answer 30

@Vocaloid

Answer 31

nope... * means multiply

Answer 32

what do multiply

Answer 33

probability of tails = 1/2

(probability of tails)*(probability of tails) = ?

Answer 34

15.5? @Vocaloid

Answer 35

um... not quite...

Answer 36

the probability of tails is 1/2

so what is

(probability of tails) times (probability of tails)?

Answer 37

still there?

Answer 38

.25? @Vocaloid

Answer 39

good

Answer 40

now for number 5 we just subtract

1 - (1/4) - (1/4)

Answer 41

that's 0
? @Vocaloid

Answer 42

no it isn't... check your math again.

Answer 43

what is 1 - (1/4)?

Answer 44

.75 @Vocaloid
