#### Question

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

at most two heads

#### Solution

When three coins are tossed, possible outcomes are:

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

Total possible outcomes=8

Favourable outcomes for at most two heads=HHT,THH,HTH,HTT,THT,TTH,TTT

Number of favoraable outcomes=7

p(at most two heads)=`7/8 `
