Step 1 :Calculate the probability of drawing a 9 or a 6 from a deck of 52 cards. There are 4 nines and 4 sixes in the deck.
Step 2 :Add the probabilities of drawing a 9 and a 6 together: \( \frac{4}{52} + \frac{4}{52} \)
Step 3 :Simplify the probability: \( \frac{8}{52} \) or \( \frac{2}{13} \)
Step 4 :\( \boxed{\frac{2}{13}} \) is the final answer for part a.
Step 5 :Calculate the probability of drawing a 2 or a spade from a deck of 52 cards. There are 4 twos and 13 spades in the deck.
Step 6 :Subtract the overlap of the 2 of spades to avoid double-counting: \( \frac{4}{52} + \frac{13}{52} - \frac{1}{52} \)
Step 7 :Simplify the probability: \( \frac{16}{52} \) or \( \frac{4}{13} \)
Step 8 :\( \boxed{\frac{4}{13}} \) is the final answer for part b.
