(C) When three coins are tossed simultaneously,the total number of possible outcomes is $2^3 = 8$.The sample space $S$ is given by: $S = \{HHH, HHT, HTH, THH, HTT, THT, TTH, TTT\}$.We are looking for the probability of getting at least $2$ tails. This includes outcomes with $2$ tails or $3$ tails.The favorable outcomes are: $\{HTT, THT, TTH, TTT\}$.The number of favorable outcomes is $4$.Therefore,the probability $P = \frac{	ext{Number of favorable outcomes}}{	ext{Total number of outcomes}} = \frac{4}{8} = \frac{1}{2}$.

In a simultaneous throw of three coins,what is the probability of getting at least $2$ tails?
