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 the survey on Saturday is the same as it was on Friday, how many customers will be selected to participate in the survey on Saturday?

Answer 1

126 customers

Explanation:

90/500=0.18

that means that 18% of all customers were surveyed.

multiplying 700 by 0.18 yields 126, which is your answer!
