प्रश्न
Two coins are tossed simultaneously. Find the probability of getting at least 1 head.
उत्तर
When two coins are tossed simultaneously, all possible
outcomes are HH, HT, TH and TT.
Total number of possible outcomes = 4
Let E be the event of getting at least one head.
Then, the favourable outcomes are HT, TH and HH
Number of favourable outcomes = 3
∴ P (getting at least 1 head) = `"Number of favourable outcomes"/"Total number of possible outcomes "= 3/4`
