(b) When we get 1, number of positive divisors are 1
When we get 2, number of positive divisors are 2
When we get 3, number of positive divisors are 2
When we get 4, number of positive divisors are 3
When we get 5, number of positive divisors are 2
When we get 6, number of positive divisors are 4
Hence range of random variable X is {1,2,3,4}
