Vedclass · Answer

(A) 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 $E$ be the event of getting $3$ heads. The favorable outcome is:$E = \{HHH\}$Therefore,the number of favorable outcomes is $n(E) = 1$.The probability of the event $E$ is given by:$P(E) = \frac{n(E)}{n(S)} = \frac{1}{8}$
