(B) When an unbiased coin is tossed $3$ times,the total number of possible outcomes is $2^3 = 8$.The sample space $S$ is given by:$S = \{HHH, HHT, HTH, THH, HTT, THT, TTH, TTT\}$.The event $A$ is defined as getting exactly $2$ heads.The favorable outcomes for event $A$ are $\{HHT, HTH, THH\}$.The number of favorable outcomes $n(A) = 3$.Therefore,the probability $P(A) = \frac{n(A)}{n(S)} = \frac{3}{8}$.

An unbiased coin is tossed thrice. Find the probability of the following event:
$A:$ Exactly $2$ heads are received.
