Answer 1

The formula for the conditional probability is:

$P(A|B)= \frac{P(A*B)}{P(B)}$

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:

$P(A|B)= \frac{ \frac{3}{10} }{ \frac{2}{5} } \\ \\ P(A|B)= \frac{3}{4}$

Therefore, option D is the correct answer.
