(C) When three coins are tossed once,the sample space $S$ is given by:$S = \{HHH, HHT, HTH, THH, HTT, THT, TTH, TTT\}$Therefore,the total number of possible outcomes is $n(S) = 8$.Let $D$ be the event of getting at least $2$ heads. The favorable outcomes are:$D = \{HHH, HHT, HTH, THH\}$Therefore,the number of favorable outcomes is $n(D) = 4$.The probability of event $D$ is given by:$P(D) = \frac{n(D)}{n(S)} = \frac{4}{8} = \frac{1}{2}$

Three coins are tossed once. Find the probability of getting at least $2$ heads.
