Expert Solution

Step 1

Probability of an event is computed by taking the ratio of number of favourable outcomes to total number of possible outcomes. The probability gives the chances of occurrence of an event.

The probability of an event A given that event B occurred is called conditional probability of A and it is computed by $P (A | B) = \frac{P (A \cap B)}{P (B)}$ . The event $A \cap B$ means the event A and B occur together.
