Question

Pls help There is a 20% chance that a customer walking into a store will make a purchase. A computer was used to generate 5 sets of random numbers from 0 to 9, where the numbers 0 and 1 represent a customer who walks in and makes a purchase.

A two column table with title Customer Purchases is shown. The first column is labeled Trial and the second column is labeled Numbers Generated.


What is the experimental probability that at least one of the first three customers that walks into the store will make a purchase?


A) 60%


B) 13%


C) 40%


D) 22%

Answer 1

it's D

Step-by-step explanation:

hope this helps lol.....

Answer 2

The experimental probability that at least one of the first three customers will make a purchase is found by examining the first three numbers of each trial set. There are 2 out of 5 sets where a purchase (represented by 0 or 1) is made, resulting in a probability of 40%.

Step-by-step explanation:

To find the experimental probability that at least one of the first three customers will make a purchase, we need to analyze the generated numbers for each trial and identify the cases where 0 or 1 appears within the first three numbers of each set.

Trial 1: The first three numbers are 2, 8, 7 - no purchases.

Trial 2: The first three numbers are 7, 0, 3 - one purchase.

Trial 3: The first three numbers are 9, 7, 2 - no purchases.

Trial 4: The first three numbers are 0, 0, 9 - two purchases.

Trial 5: The first three numbers are 6, 7, 9 - no purchases.

There are 2 out of 5 trials where at least one customer in the first three makes a purchase. Therefore, the experimental probability is 2 out of 5, which is 40%. The correct answer is C) 40%.
