Question

Marlene is playing Skee Ball at her favorite arcade. She wants to determine the likelihood that she'll roll a ball into each hole. So, she rolls several times and records her results in the following table. Points Scored Frequency 10 23 20 12 30 6 40 8 50 1 A. On any given roll, the experimental probability that Marlene will get 30 points is . B. On any given roll, Marlene is most likely to get

Answer 1

Hello!

First it will help if you list the numbers from least the greatest.

1, 6, 8, 10, 12, 20, 23, 30, 40, 50

To find the experimental probability you count all the numbers in the data which is 10

The you count the amount of 30's which is 1

So the is a 1 out of 10 chance she will get 30 points which is 10%

To find out what number she is most likely to get you first add all of the numbers together and divide by the amount of numbers to get the average.

1 + 6 + 8 + 10 + 12 + 20 + 23 + 30 + 40 + 50 = 200

Then divide 200 by the amount of numbers you added which is 10

200/10 = 20

She is most likely to get 20 on any given role

The answer for A is 1/10 or 10%

The answer for B is 20 points

Hope this helps!
