a) The answer to the question "What is the probability that in a random draw of five cards from a deck, all of them are spades?" was given in the lecture as C13,5/C52,5. A student objected, and said that the probability of drawing the first spade is 5213, drawing a spade again is 5112, and so forth, so that the probability of drawing five spades is 5213511250114910489. What do you say?.
