Hi,
I'm taking the probability class and came across some practice problems from an online course. What's the best way to approach this problem?

Suppose that 10 cards, of which five are red and five are green, are placed at random in 10 envelopes, of which five are red and five are green. Determine the probability that exactly two envelopes will contain a card with a matching color.

Probability of that happening is 0, as it is impossible to put exactly 2 cards in their matching coloured envelope.For ex, if we 2 red cards into 2 red envelopes, then we will have left 3 red envelopes and 5 green envelopes to put 5 green and 3 red cards, which ensures that this is an impossible event.
