Question
Five mangoes and 4 apples are in a box. If two fruits are chosen at random, find the probability that one is a mango and the other is an apple
Solution
Let S be the sample space
A be the event of taking one mango and one apple.
n(S) = 9C2
n (A) = 5C1 × 4C1
= 5 × 4
= 20
P(A) = `("n"("A"))/("n"("S"))`
= `20/36`
= `5/9`
