# Give answer to 74 and 75 question

**Q74**

Number of total outcomes , n(S) = 100

Event of getting a number divisible by 10

A={10,20,30,40,50,60,70,80,90,100}

n(A)=10

So

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

=10/100

=1/10

**q-75**

Number of total outcomes when a perfect die is thrown twice, n(S) = 36

Event of getting total of 9

A = {(3,6), (4,5), (5,4), (6,3)

= > n(A) = 4

So

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

=4/36

=1/9
