Question
Please how do I solve Questions 2.56 and 2.58
a How many different samples of 10 nurses can be selected? employed b Twenty of the 90 nurses are male. If 10 nurses are randomly selected from those ou dide by the hospital, what is the probability that the sample of ten will include exactly 4 ma (and 6 female) nurses? 2.56 2.57 2.58 2.59 2.60 2.61 A student prepares for an exam by studying a list of ten problems. She can solve six of them. For the exam, the instructor selects five problems at random from the ten on the list given to the students. What is the probability that the student can solve all five problems on the exam? Two cards are drawn from a standard 52-card playing deck. What is the probability that the draw will yield an ace and a face card? Five cards are dealt from a standard 52-card deck. What is the probability that we draw a 3 aces and 2 kings? b a "full house" (3 cards of one kind, 2 cards of another kind)? Five cards are dealt from a standard 52-card deck. What is the probability that we draw a 1 ace, 1 two, 1 three, 1 four, and 1 five (this is one way to get a "straight")? bany straight? Refer to Example 2.7. Suppose that we record the birthday for each of n randomly selected persons. a Give an expression for the probability that none share the same birthday. b What is the smallest value of n so that the probability is at least .5 that at least two people share a birthday? Suppose
