In a school there are 1000 students, out of which 430 are girls. It is known that out of 430, 10% of the girls study in class XII. What is the probability that a student chosen randomly studies in class XII given that the chosen student is a girl?

Explanation

Here,

`A = `Event that chosen student is a girl.

`:. P(A) = 430/1000 = 43/100`



Let `B = `Event that chosen student studies in class XII.

`P(B) = 10% = 10/100 = 1/10`
