# A coin is tossed 3 times. List the possible outcomes. Find the probability of getting at least 2 heads

**Solution:**

Given, a coin is tossed 3 times.

We have to find the probability of getting at least 2 heads.

When a coin is tossed three times.

The possible outcomes are {TTT, HHH, TTH, THT, THH, HTT, HTH, HHT}

Number of possible outcomes = 8

Favourable outcomes = {THH, HTH, HHT, HHH}

Number of favourable outcomes = 4

Probability = number of favourable outcomes / number of possible outcomes

Probability of getting all heads = 4/8

Therefore, the probability of getting all heads = 1/2
