d) ) What is the probability of drawing the 4 of spades or a club?

These two separate probabilities are 1/52 and 13/52, and they're mutually exclusive so you just add them: 5/52

c) What is the probability of drawing the jack of hearts and then the jack of diamonds?

P(J of hearts) is 1/52. Then 51 other cards would remain; P(J of diamonds) = 1/51. Multiply these to get answer.

e) What is the probability of drawing a 3 or a spade? There are 4 threes and 13 spades, but one of the spades is a 3.

To satisfy the 'event' described in this problem, there are 16 possible draws, out of the 52 cards; P(event 'e') = 16/52 which reduces to 4/13.
