Question

Two coins are tossed simultaneously. What is the probability of getting at most one tail?

Sum

Solution

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`
