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` |
