प्रश्न
Two coins are tossed simultaneously. What is the probability of getting at most one tail?
उत्तर
When 2 coins are tossed
Possible outcomes = HH, TH, HT, TT
Now, Outcomes with at most with 1 tail = HH, HT, TH
Thus, P(getting at most 1 tail) = `"Number of outcomes with almost 1 tail"/"Total number of outcomes"`
= `3/4`
