Step 1

**Conditional probability:**

The conditional probability describes that the probability of an event *B* occurs given another event *A* has already occurred. Usually, the conditional probability is denoted as *P*(*B*|*A*).

Step 2

**Computation of P(A):**

Suppose, the two events *A* and *B* are not independent, then the probability of *A* and *B* is defined as follows.

*P*(*A* and *B*) = *P*(*A*) **×** *P*(*B*|*A*)

Here, *P*(*A* and *B*) is 0.04 and *P*(*B*|*A*) is 0.87.

Substituting the values in the above formu...
