Question

I will be getting temporary zeroes in the subject pretty soon on the twenty-seventh of May, and I need someone such as a qualified tutor to help me with the quiz. I will medal anyone who gives me the right answer and walks me through the subject for the ten questions.

The table shows the results of spinning a four-colored spinner fifty times. Find the experimental probability and express it as a decimal.

P(not red)

Red=20, Blue= 10, Green=9, Yellow=11.

A.) 0.6
B.) 0.4
C.) 0.2
D.) 0.3.

All spins amount to fifty, I divided the fifty by the colors that were not red.

Answer 1

right

Answer 2

I chose answer choice C.), which is the decimal 0.2.

2.) You roll a number cube 20 times. The number 4 is rolled 8 times. What is the experimental probability of rolling a 4?

A.) 40% <-----
B.) 25%
C.) 20%
D.) 17%.

(I multiplied 20x8=160, then divided by 4 which is 40 so I choose 40%.)

3.) The table below shows the results of flipping two coins. How does the experimental probability of getting at least one tails compare to the theoretical probability of getting at least one tails?

HH=28, HT=22 TH=36, TT=16

A.) The experimental probability is 3% greater than the theoretical probability. <----
B.) The theoretical probability is 3% greater than the experimental probability.
C.) The experimental probability is equal to the theoretical probability.
D.) The experimental probability is 1% greater than the theoretical probability.

(The theoretical probability is 25, and the experimental probability is 30. I choose answer A.)

Answer 3

hold the phone

Answer 4

the first one, you said you divided all that were not red by 50
that is the correct procedure
what did you get?

Answer 5

I got 0.6.

Answer 6

yeah that is right, but it is not C, C is 0.2

Answer 7

Okay, so would it be my original answer response 0.6? I got 0.2 after someone told me to divide 0.6 by 3.

Answer 8

yes it is 0.6

Answer 9

Okay thank you! Alright as for the second, and third question? Are my answer choices correct? I am not one-hundred percent sure on question number three.

Answer 10

You roll a number cube 20 times. The number 4 is rolled 8 times. What is the experimental probability of rolling a 4?

Answer 11

eight times out of twenty
or \(\frac{8}{20}\) or reduce or turn in to a decimal

Answer 12

your explanation
"I multiplied 20x8=160, then divided by 4 which is 40 so I choose 40%.) " not to be mean or anything, but it is not right
first off, the number 40 is not 40%
\(40\%=0.4=\frac{2}{5}\)

Answer 13

second, the number "4" in the question has nothing to do with it, it would be the same answer if they said, "roil a die 20 times the six come up 8"

Answer 14

ready for the next one?

Answer 15

Yes.

Answer 16

HH=28, HT=22 TH=36, TT=16

how many rolls total?

Answer 17

102 rolls.

Answer 18

and how many have "at least one tail"?

Answer 19

Three.

Answer 20

oh on

Answer 21

\[HH=28, \color{red}{HT=22 ,TH=36, TT=16} \] all those have at least one tail

Answer 22

how many total have at least one tail?

Answer 23

Three

Answer 24

maybe it is not clear what the numbers mean there

Answer 25

HH 28 means 28 times you got 2 heads, not one time

Answer 26

Ohhh...

Answer 27

Okay so I've got that one now.

I understand the others, so now I just need help with three questions and then I am out of your hair.

A coin is tossed and then a number cube is rolled. What is P(heads a number less than 5)?

1/3
5/12
2/3
5/6. <----

What is the probability of rolling a number cube and getting 4 and then an even number?

1/6
1/2
1/12
2/3<----

A bag of fruit contains 4 apples, 1 plum, 2 apricots, and 3 oranges. Pieces of fruit are drawn twice with replacement. What is P(apple, then apricot?)

4/5
2/25
3/25
3/5. <-----

Answer 28

A coin is tossed and then a number cube is rolled. What is P(heads a number less than 5)?

Answer 29

it is not \(\frac{5}{6}\)

Answer 30

how many numbers less than 5?

Answer 31

There are three

Answer 32

name then

Answer 33

Two, three, and four.

Answer 34

you missed one

Answer 35

Oh and one.

Answer 36

so how many total?

Answer 37

Four out of five or 4/5

Answer 38

how many sides does one die have?

Answer 39

6.

Answer 40

right, so not four out of five
try again

Answer 41

Okay, so would it be two-thirds?

Answer 42

yes but that is not the final answer

Answer 43

Okay so reducing it completely would be 1/3

Answer 44

what is the probability you toss heads on a coin

Answer 45

yes\[\frac{1}{2}\times \frac{2}{3}=\frac{1}{3}\]

Answer 46

What is the probability of rolling a number cube and getting 4 and then an even number?

Answer 47

what is the probability you roll a 4 on one die?

Answer 48

1/6

Answer 49

yes, and the probability you roll an even number?

Answer 50

3/6

Answer 51

yes
multiply those two numbers \[\frac{1}{6}\times \frac{3}{6}\]

Answer 52

It is 0.08% in a percentage and 1/12 as a fraction

Answer 53

yes

Answer 54

A bag of fruit contains 4 apples, 1 plum, 2 apricots, and 3 oranges. Pieces of fruit are drawn twice with replacement. What is P(apple, then apricot?)

Answer 55

find the probability you get an apple, then the probability you get a pear, then multiply

Answer 56

There are no pears?

Answer 57

oops i means "apricot"

Answer 58

Okay, the probability to get an apple would be 4/10, or 40% and the probability of getting an apricot would be 2/10 or 20%. With these, you would multiply 4/10x2/10, correct?

Answer 59

yes

Answer 60

Alright, perfect! Thank you for your help. It is greatly appreciated. And how do you give a metal or do you automatically get that?

Answer 61

Okay I figured it out, you have two medals.
