I have a deck of 15 cards 5 of which are red, 5 are blue and 5 are green. The cards are in a random order and I turn them over, one at a time: Card 1, Card 2, ..., Card 15 without replacement. Evaluate the following probabilities. (a) Card 3 is blue: (b) Card 1 is red and Card 2 is not blue: (c) Card 5 is red or Card 9 is blue: (d) Card 2 is green given that Card 1 is green: (e) A colour appears more than once in the first 3 cards
