Question

Three coins are tossed together. Write all the possible outcomes. Now, find the probability of getting exactly two heads.

Answer 1

When three coins are tossed, possible outcomes are: 

HHH, HHT, HTH, HTT, THH, THT, TTH, TTT  

Total possible outcomes = 8 

Favorable outcomes for exactly two heads = HHT, THH, HTH 

Number of favorable outcomes = 3 

P(exactly two heads) = `3/8`
