(C) When three unbiased coins are tossed simultaneously,the total number of possible outcomes is $2^3 = 8$.These outcomes are: $\{HHH, HHT, HTH, THH, HTT, THT, TTH, TTT\}$.We are looking for the probability of receiving at least two heads.The favorable outcomes are those that contain two or three heads: $\{HHT, HTH, THH, HHH\}$.The number of favorable outcomes is $m = 4$.Therefore,the required probability $P = \frac{m}{n} = \frac{4}{8} = \frac{1}{2}$.

Three unbiased coins are tossed simultaneously. Then,the probability of receiving at least two heads is ..........
