Question

Five cards are dealt from a shuffled deck. What is the probability that the
dealt hand contains a. exactly one ace; b. at least one ace?

Answer 1

Answer:

Step-by-step explanation:

Or just the probability of an ace appearing in a 5-card hand? If you want exactly one ace, then your answer is correct. (525) is the number of 5-card hands in the deck, and you have 4 choices for which ace to include (hence, (41)), and 48 choose 4 choices for the other 4 cards (hence, (484)).

Answer 2

Answer:

a.4/52=1-1/13=0.9

b.1/13
