Question

For the past 40 days, Naomi has been recording the number of customers at her restaurant between 10:00 am and 11:00 am. During that hour, there have been fewer than 20 customers on 25 out of the 40 days. What is the experimental probability there will be 20 or more customers on the forty first day?

(Pls help this is due tm)

Answer 1

Answer: 0.375 or 37.5%.

Explanation:

To calculate the number of days with 20 or more customers, subtract the days with fewer than 20 customers from the total number of days:

Day(s) with 20 or more customers = 40 - 25 = 15

So, out of the 40 days, 15 days had 20 or more customers between 10:00 and 11:00 a.m. As a result, the likelihood of 20 or more customers on the forty-first day is:

Probability = number of occurrences of event / total number of trials

15/40 is the probability.

0.375 is the probability.

As a result, the probability of there being 20 or more customers between 10:00 and 11:00 a.m. on the forty-first day is 0.375, or 37.5%.
