# A Coin is Tossed Twice. Find the Probability of Getting: Exactly One Tail - Mathematics

Sum

A coin is tossed twice. Find the probability of getting: exactly one tail

#### Solution

Exactly one tail

Possible number of favourable outcomes = 2 (i.e. TH and HT)

Total number of possible outcomes = 4

∴ P(E) = "Number of favourable outcomes"/"Total number of possible outcomes"

= 2/4 = 1/2
