A simple survey consists of three multiple choice questions. The first question has 5 possible answers, the second has 3 possible answers and the third has 4 possible answers. In how many different ways can you complete this survey? use counting rule method
If one operation can be done in n1 ways, a second
operation
can be done in n2 ways and the third operation done n3 ways then
the number of different ways of doing is n1*n2*n3
5*3*4 =60
You can complete this survey in 60 ways.
