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? ______ customers on Saturday (Write the number only***)

Answer 1

126

Explanation:

The probability is 90/500 = 18%

So, from 700 customers,

700 * 18% = 700 * 18/100 = 126

Therefore, 126 customers will be selected on saturday.
