Mark the correct alternative in each of the following: In a college 30% students fail in Physics, 25% fail in Mathematics and 10% fail in both. One student is chosen at random. The probability that she fails in Physics if she has failed in Mathematics is

Mark the correct alternative in each of the following:
In a college 30% students fail in Physics, 25% fail in Mathematics and 10% fail in both. One student is chosen at random. The probability that she fails in Physics if she has failed in Mathematics is

A = Failing in Physics

B = Failing in Mathematics

P(A) = 30%

P(B) = 25%

→ (Given)

P(A∩B) = 10%

Now we know,
