Actuary Probability
Need help with this question. I can't figure out what I'm doing wrong and the problem is throwing me off by not saying which brand specific.
A cooler contains 15 cans of Coke and 10 cans of Pepsi. Three are drawn from the cooler without replacement. What is the probability that all three are the same brand?

Hey sshort1024.
Are you aware of the hypergeometric distributions (including the one with more than two outcome types)?

(Remember: the key is without replacement).
