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 survey on Saturaday

The probability is 90/500 = 18%
So, from 700 customers,
[tex]700 * 18[/tex]% [tex] = 700 * \frac{18}{100} = 126[/tex]
Therefore, 126 customers will be selected on saturday.

Hope this helps :)

The number of customers will be selected to participate in survey on Saturaday is 126.

Given that,

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.

Based on the above information, the calculation is as follows:

The probability is [tex]= 90\div 500[/tex] = 18%

Now forr 700 customers, it should be

[tex]= 18\% \times 700[/tex]

= 216
