Question

The probability of obtaining oranges at a local market is
`(1)/(4)` and that of mangoes is
`(2)/(5)`. Find the probability that a student will obtain oranges and not mango in the market?

Answer 1

3/20

Explanation:

let P(A)=P(Oranges)

P(B)=P(mangoes)

P(not B)=1-2/5=3/5

P(A not B)=1/4×3/5=3/20
