purchase. Today the calls will go to 2 homes randomly selected from last week's 5 customers. How many different groups of customers could the store call?

Answer 1

10 different groups of customers could the store call

Explanation:

Given the data in the question;

calling two (2) homes out of last week's five (5) customers;

so, there are 5 customers from last week and todays call needs to go to 2 customers randomly;

hence, Total group will be;

`\left[\begin{array}{ccc}5\\2\\\end{array}\right]` = 5! / ( 2! × ( 5 - 2 )!

= 5! / (2! × 3! )

= 10

Therefore, 10 different groups of customers could the store call
