<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.

Let's suppose someone flips a fair coin three times.
1. The outcomes of the coins are,
Therefore, there are 8 outcomes.
2. The probability of getting exactly one tail is,
P(X=1) = 2/8 = 1/4
3. The probability of getting at most two tails is,
P(X≤2) = P(X=1) + P(X+2) = 1/4 + 1/2 = 3/4
