PROBABILITY WORKSHEET 1. In the small town of Beaumont, TN there were 128, 023 deaths in 2003. Of this total 3010 were from terminal emphysema and 6541 deaths were caused by gunshot injuries. Based on these data, predict the probability that . . . a. . . . the next person to die will die of emphysema. b. . . . the next person to die will die of emphysema or gunshot injury. 2. Assuming a 1:1 sex ratio, what is the probability that a family of six children will consist of . . . a. three boys and three girls? b. a boy, a girl, a boy, a girl, a boy and a girl, in this order? c. all boys? d. all the same sex? e. at least four boys? 3. Two newlyweds have normal pigmentation, and each has a parent with the classic albino phenotype, a recessive autosomal trait. What is the probability that, if they have five children . . . a. none will be albino? b. all will be albino? c. three will be normal and two will be albino? 4. What is the probability that a family of seven children produced by the parents in question 3 will consist of three normal girls, one normal boy, one albino girl and two albino boys, in no specified order? 5. In Mendel’s two-factor cross he obtained 315 round yellow, 101 wrinkled yellow, 108 round green and 32 wrinkled green seeds out of 556 F2 individuals. What is the probability of getting exactly these results? (NOTE! Set up the problem by showing your equation and plugging in the values, but do not compute. Repeat: DO NOT COMPUTE.)
