Question

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

Answer 1

For three coins, the total possible outcomes are 2³ = 8 because each coin has 2 possible outcomes (Head or Tail).

The outcomes where exactly two tails occur are:

1. TTH
2. THT
3. HTT

There are 3 outcomes with exactly two tails out of 8 total outcomes.

P (Exactly two tails)= `3/8`
