A coin is tossed two times. Find the probability of getting at most one head

Solution:

Given, a coin is tossed two times.

We have to find the probability of getting at most one head.

When a coin is tossed two times.

The possible outcomes are {TT, HH, TH, HT}

Number of possible outcomes = 4

Favourable outcomes = {TT, HT, TH}

Number of favourable outcomes = 3

Probability = number of favourable outcomes / number of possible outcomes

Probability of getting at most one head = 3/4

Therefore, the probability of getting at most one head is 3/4.
