A deck of playing cards contains 52 cards, four of which are aces. What is the probability that the deal of a five-card hand provides:
a. What is the appropriate probability distribution for X? Explain how X satisfies the properties of the distribution.
b. A pair of Aces?
c. Exactly one ace?
d. No aces?
e. At least one ace?
a. I don't know what X signifies.
b. First find the probability of two aces, then 3 non-aces.
(4/52)(3/51)(48/50)(47/49)(46/48) = ?
c, d. Use similar to process above.
e. At least one ace = 1, 2, 3, or 4 aces. Use answers from b and c, plus calculate probability of 3 aces and 4 aces.
The probability of either-or = sum of individual probabilities.
