Homework Answers
Total no. of customers = 100+66+---+97 = 507
1.
Total no. of customers between age group 20 to 40 are 66 + 83 = 149
Probability = 149 / 507 = 0.2939
2.
Customer either older than 60 or younger than 40 = 100+66+83+97 = 346
Probability = 346 / 507 = 0.6824
3.
Customer at least 60 = 97
Probability = 97 / 507 = 0.1913
