WebFeb 13, 2024 · Therefore p is equal to 0.667 or 66.7%. Calculate the number of combinations (5 choose 3). You can use the combination calculator to do it. This number, in our case, is equal to 10. Substitute all these values into the binomial probability formula above: P (X = 3) = 10 × 0.6673 × (1-0.667)(5-3) = 10 × 0.6673 × (1-0.667)(5-3)
