A coin is tossed four times. What is the probability that there is at the least one tail?	Choose the most appropriate option:
A) 15/16 B) 31/37 C) 31/18 D) 31/10 E) 31/19
Let P(T) be the probability of getting least one tail when the coin is tossed four times.   = There is not even a single tail.   i.e. all the outcomes are heads.   = 1/16 ; P(T) = 1 - 1/16 = 15/16   15/16nswer: 15/16
