Solution

Rahim tosses two coins simultaneously. The sample space of the experiment is {HH, HT, TH, TT}.

Total number of outcomes = 4

Outcomes in favour of getting at least one tail on tossing the two coins =
{HT, TH, TT}

Number of
outcomes in favour of getting at least one tail = 3

∴ Probability of getting at least one tail on tossing the two coins `="Number of outcomes in favour"/"Total number of outcomes"=3/4`
