Homework: Chapter 4 (Probability)

From Moore and McCabe:
4.23 Probability of no failure in 12 independently selected computer chips used in a car
4.30 Distribution of two variables depicted in a two-way table
4.34 Distribution of number of girls in a family planning to have four children
4.42 Normal probabilities
4.58 Computing means and standard deviations and comparing the distribution of household size with the distribution of family size
4.103 Do random strings have long runs? (Computer simulation)

It is expected that the faculty in each section will provide additional questions.
