Refer to the values we have previously determined, N = 15, M = 9, n = 6, and k = 6. The remaining values needed for the formula are N - M and n - k.
Find N - M.
NM = 15 - 9

Find n - k.
n-k= 6 - 6

Step 5
Refer to these values from the previous step.
N = 15, M = 9, n = 6, k = 6, N - M = 6, n k = 0
Substitute these values into the hypergeometric probability formula, or use technology. Round your final answer to four decimal places.

A candy dish contains nine brown and six red M&Ms. A child selects six M&Ms without checking the colors.
What is the probability that all the M&Ms are brown?
Step 1
First, we need to make sure the hypergeometric distribution is appropriate for this sample. We check that 0.05, where n = 6 is the number of M&Ms being selected, and N

Step 2
Recall that a hypergeometric distribution population contains M successes and N M failures. Consider drawing a brown M&M to be a success and a red M&M to be a failure.
Given a total of nine brown and six red M&Ms in the dish, the total number of M&Ms was found in the previous step to be N = 15, and the total successes (or brown M&Ms) is M = 9

Refer to the formula below for the probability of exactly k successes in a random sample of size n.

With nine brown M&Ms in a bowl of fifteen M&Ms, we know M = 9 and N = 15. The remaining variables are the sample size n and the number of successes k. We know that six M&Ms are drawn, and we are calculating the probability of having
exactly six brown M&Ms in that sample. Thus, in the sample of size n = 6

the number of successes, or brown M&Ms, is k = 6
