1. Consider a family with 3 boys and 2 girls who received placebo. Suppose that each child's survival is independent of all the other children in the family. Calculate the probability that 0, 1, 2 or 3 boys die during the study follow-up. Use the applet: http://homepage.stat.uiowa.edu/~mbognar/applets/bin.html

2. Use the Poisson approximation to the binomial distribution to recalculate probabilities of 0, 1, 2 or 3 boys dying in problem 1. Use the applet:
