The probability of getting heads while flipping a coin for three times is 1/2
<u>Explanation:</u>
When a coin is flipped then there are two possible outcomes.
We can either get a heads or a tail.
If a coin is flipped three times and the possibility of getting heads would be 3
Total number of outcomes would be 6 ( 2 possible outcomes X 3 times toss)
Therefore, probability of getting heads would be = 3/6
= 1/2
Therefore, the probability of getting heads while flipping a coin for three times is 1/2
