Need a step-by-step solution for Q1, Q2, and Q3.

1. You read in a book on poker that the probability of being dealt a straight flush in a five-card poker hand is 1/64,974. This means that A. if you deal millions of poker hands, the fraction of them that contain a straight flush will be very close to 1/64,974. B. if you deal 64,974 poker hands, exactly one of them will contain a straight flush. C. if you deal 6,497,400 poker hands, exactly 100 of them will contain a straight flush. D. if you deal 6,497,400 poker hands, more than 100 of them will contain a straight flush. 2. Let A be the event that the student is enrolled in a four-year college and B the event that the student is female. The proportion of females among students enrolled in a four-year college is expressed in probability notation as A. P(A n B). B. P(A|B). C. C. P(B|A). D. P(B). 3. Let A be the event that a flight from New York to San Francisco arrives on time and let B be the event that it is a clear day in San Francisco. Suppose the probability of a clear day is P(B) = 0.6 and the probability a plane arrives on time is P(A) = 0.7. We also know that the probability a plane arrives on time on a cloudy day is P(A|BC) = 0.5. The events A and B are: A. dependent events. B. independent events. C. disjoint events. D. complementary events
