Prob. 1. Adults are randomly selected for a Gallup survey and asked if they believe that human cloning should be allowed or not. Among randomly selected adults and respondents, 91 said cloning of living (human) beings should be allowed, 901 said no, and 20 abstained from voting. Based on this data, estimate the probability that a person is randomly chosen. Consider that human cloning should be allowed.

Prob. 2. Determine the probability that exactly two of the three children of a partner are male. Suppose it is equally likely to give birth to a boy who, a girl, and that the gender of any child DOES NOT influence the gender of the other child. Prob 3. At her first date, Maria asks John to guess his birth date, omitting the year. How likely is John to guess correctly? (Ignore leap years)
