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 PA|B=PABPB. When two events are mutually exclusive then the events cannot occur together and thus PAB=0.
