Question
12.)Which of the following numbers could be the probability of an event? 1.5, 1/2, 3/4, 2/3, 0, 1/4
34.)More Genetics In Problem 33, we learned that for some diseases, such as sickle-cell anemia, an individual will get the disease only if he or she receives both recessive alleles. This is not always the case. For example, Huntington’s disease only requires one dominant gene for an individual to contract the disease. Suppose that a husband and wife, who both have a dominant Huntington’s disease allele (S) and a normal recessive allele (s), decide to have a child.
a.)List the possible genotypes of their offspring.
b.)What is the probability that the offspring will not have Huntington’s disease? In other words, what is the probability that the offspring will have genotype ss? Interpret this probability. 40.)Which of the assignments of probabilities should be used if the coin is known to be fair?
48.)Classifying Probability Determine whether the probabilities below are computed using classical methods, empirical methods, or subjective methods.
a.)The probability of having eight girls in an eight-child family is 0.00390625.
b.)On the basis of a survey of 1000 families with eight children, the probability of a family having eight girls is 0.0054.
c.)According to a sports analyst, the probability that the Chicago Bears will win their next game is about 0.30.
d.)On the basis of clinical trials, the probability of efficacy of a new drug is 0.75.
32.)A Deck of Cards A standard deck of cards contains 52 cards One card is randomly selected from the deck.
a.)Compute the probability of randomly selecting a two or three from a deck of cards.
b.)Compute the probability of randomly selecting a two or three or four from a deck of cards.
c.) Compute the probability of randomly selecting a two or club from a deck of cards.

26. Family Structure The following probability model shows the distribution of family structure among families with at least one child younger than 18 years of age in 2013 Family Structure Two married parents, first marriage Two married parents, one Single parent No parent at home Probability 0.46 or both remarried 0.15 0.34 0.05 Source: Pew Research a. Verify that this is a probability model. b. What is the probability that a randomly selected family with at least one child younger than 18 years of age in 2013 had two married parents in their first marriage? Interpret this probability.Explanation / Answer
answer
12.)Which of the following numbers could be the probability of an event? 1.5, 1/2, 3/4, 2/3, 0, 1/4
answer........>1/2 , 3/4, 2/3, 0
26) a)yes it's probability model
b)0.46
32)
a)
number of cards which is two or three = 4*2 = 8
probability of randomly selecting two or a three = 8/52
b)
number of cards which is two or three or four = 4*3 = 12
probability of randomly selecting an two,three or four= 12/52
c) number of cards which is two or club = 13+ 3*1 = 16
probability of randomly selecting a two or club = 16/52
