Question

How many numbers from 1 to 50 are divisible by 13?

Answer 1

Answer:

3 numbers from 1 to 50 are divisible by 13?

Answer 2

Answer:

S={1,2,3,4...50} n(s)= 50

Events A = Divisible by 13 A={26,39} ...don't take 13

n(A)= 3

P(A) = n(A)/n(S)

P(A) = n(A)/n(S) =2/ 50

P(A) = n(A)/n(S) =2/ 50

A= 25
