Binomial Distribution (Optional) · Exercise 29
Let X = the number of games won in that upcoming month.
According to the World Bank, only 9 percent of the population of Uganda had access to electricity as of 2009. Suppose we randomly sample 150 people in Uganda. Let X = the number of people who have access to electricity.
(a) What is the probability distribution for X?
(b) Using the formulas, calculate the mean and standard deviation of X.
(c) Use your calculator to find the probability that 15 people in the sample have access to electricity.
(d) Find the probability that at most 10 people in the sample have access to electricity.
(e) Find the probability that more than 25 people in the sample have access to electricity.
