Give answer to 74 and 75 question
dear student
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
