Mark (√) against the correct answer in each of the following: In a class, 60% of the students read mathematics, 25% biology and 15% both mathematics and biology. One student is selected at random. What is the probability that he reads mathematics if it is known that he reads biology?

Question

Philoid · Accepted Answer

_Given:

60% of the students read mathematics, 25% biology and 15% both mathematics and biology

That means,

Let the event A implies students reading mathematics,

Let the event B implies students reading biology,

Then, P(A) = 0.6

P(B) = 0.25

P(AB) = 0.15

We, need to find P(A/B) = P(AB)/ P(B)

⇒
