Question

At a store, customers are randomly selected to participate in a survey. On Friday, there were 500 customers at the store. Of those, 90 were selected to participate in the survey. On Saturday, the store manager expects 700 customers in the store. If the probability of being selected to participate in a survey on Saturday is the same as it was on Friday, how many customers will be selected to participate in the survey on Saturday? BIG SHOUTOUT TO THE PERSON FROM LAST QUESTION!!!

Answer 1

There will most likely be 1200 people participating

Answer 2

The probability of being selected on Friday was 90/500 = 9/50. Since the probability of being selected on Saturday is the same as it was on Friday, we can use this probability to calculate how many customers will be selected to participate in the survey on Saturday.

If there are 700 customers at the store on Saturday, then we can calculate the number of customers that will be selected for the survey as follows:

Probability of selection = 9/50 Number of customers = 700

Number of customers selected for survey = Probability of selection * Number of customers = (9/50) * 700 = 126 customers

Therefore, we can expect that 126 customers will be selected to participate in the survey on Saturday.
