an experiment consist of three parts. there are five ways to accomplish the first part. four ways to accomplish the second part. and three ways to acomplish the third part. The total number of ways to acomplish the experiment is:

60

12

20

15

Solution

No.of ways to accomplish the first part = 5

No.of ways to accomplish the second part = 4

No.of ways to accomplish the third part= 3

Hence total no.of ways to acomplish the experiment = 5*4*3 = 60 i.e. Option (A).
