Raju tosses two different coins simultaneously what is the probability of getting at least one head

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}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`
