(C) When $3$ coins are tossed,the total number of possible outcomes is $2^3 = 8$. The sample space is $S = \{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT\}$.We need to find the probability of getting at least $1$ head and $1$ tail. This means we exclude the cases where all outcomes are heads $(HHH)$ or all outcomes are tails $(TTT)$.The favourable outcomes are $\{HHT, HTH, HTT, THH, THT, TTH\}$.The number of favourable outcomes is $6$.Required probability $= \frac{	ext{Number of favourable outcomes}}{	ext{Total number of outcomes}} = \frac{6}{8} = \frac{3}{4}$.
