Expert Solution

Step 1

If the probability of getting selected for each outcome is equal then such outcomes can be termed as equally likely outcomes. For equally likely outcomes, the probability of favorable event can be given by dividing the number of favorable outcomes, with the total number of outcomes.

$Probability of favorable event = \frac{Number of favorable outcomes}{Total number of outcomes}$

If happening/not happening of one event does not affect the happening/not happening of other event, then such events can be termed as independent events. If $A$ and $B$ are two independent events, then $P (A \cap B) = P (A) \cdot P (B)$ .
