Russel Gajate: Its all about multiplying your choices. You just need to ask yourself how many choices do you have.2.28 A drug for relief of asthma can be purchased from 5 different manufacturers in liquid, tablet, or capsule form, all of which come in regular and extra strength. how many different ways can a doctor prescribe the drug for a patient suffering from asthma? 5 * 3 * 2 = 302.38 four married couples have bought 8 seats in the same row for a concert. In how many different ways can they be seateda. with no restrictions?8*7*6**4*3*2*1 = 40320b. if each couple is to sit together?8*1*6*1*4*1*2*1 = 384c. If all the men sit together to the right of all the women?4*1*3*1*2*1*1*1 = 242.48 Nine people are going on a skiing trip in 3 cars that hold 2, 4, and 5 passengers, respectively.

An envelop may be purchased for $25. What is the sample space for the different amounts of money? X(FX): 100(75) 25(150) 10(275)Assign probabilities to the sample points and then find the probability that the first envelop purchased contains less than $100.X(PX): 100(.15) 25(.30) 10(.55).30 + .55 = .852.79 A random sample of 200 adults are classified below by sex and their level of education attained.EDUCATION MALE FEMALEelementary 38 45secondary 28 50college 22 17If a person is picked at random from this group, find the probability thata. the person is male, given that the person has a secondary education;(28+22)/(200-38-45) = 40/117 = .34b. the person does not have a college degree, given that the person is a female.EDUCATION MALE FEMALEelementary 38 45secondary 28 50college 22 1790/(90+17) = .842.83 In USA today (Sept. 5 1996) the results of a survey ! involving the use of sleepwear while travelling were listed as! follows:MALE FEMALE TOTALunderwear 0.220 0.024 0.244nightgown 0.002 0.180 0.182nothing 0.160 0.018 0.178pajamas 0.102 0.073 0.175T-shirt 0.046 0.088 0.134Other 0.084 0.003 0.087a. what is the probability that a traveler is a female who sleeps in the nude?.018b.
