Question

Three different coins are tossed .Find the probability of getting exactly one head

Answer 1

Possible outcomes = HHH, HHT, HTH, THH, TTT, TTH, THT, HTT

No. of possible outcomes = 8

Favourable outcomes = TTH, THT, HTT

No. of favourable outcomes = 3

Probability = No. of favourable outcomes/ No. of possible outcomes

Probability= 3/8
