Default At least one black.

Whats the probability of drawing at least one black card while drawing 3 cards from a standard deck of cards.

Just checking a question I am unsure about from my math final.

Default Re: At least one black.

P(drawing 3 reds) = 26/52 * 25/51 * 24/50 = .118

P(drawing at least 1 black) = 1 - P(drawing 3 reds) = .882
