A coin is tossed three times. What is the probability that there is at the least one tail?
Choose the most appropriate option.
A) 7/8	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 three times.   = There is not even a single tail.   i.e. all the outcomes are heads.   = 1/8 ; P(T) = 1 - 1/8 = 7/8   7/8nswer: 7/8
