<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,
- HHH
- HHT
- HTH
- HTT
- TTH
- THT
- TTH
- TTT
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

This is a division problem. First, get 12 1/3 into fraction form instead of mixed number form to make your life easier;
Now, divide the two fractions. Since this is fraction division, the reciprocal is flipped and the two fractions multiplied.
The answer from the fraction division is 16 and four-ninths, but because you need a whole number as an answer,
the answer is 16 pieces.
