Answer 1

The formula for the conditional probability is:


`P(A|B)= (P(A*B))/(P(B))`

This indicates the probability of event A, given that event B has already occurred.

Here P(A*B) indicates P(A∩B).

Using the given values, in the formula, we can write:


`P(A|B)= ( (3)/(10) )/( (2)/(5) ) \\ \\ P(A|B)= (3)/(4)`

Therefore, option D is the correct answer.
