The chance of contracting strep throat when coming into contact with an infected person is estimated as 0.15. Suppose the four children of a family come into contact with an infected person. Conduct a simulation to answer the following questions. Use the random number table below and conduct 20 trials. Clearly identify each trial on the table.

a.) Using your results estimate the average number of children who will get the disease

b.) What is the probability of two of the children getting the disease?

c.) What is the probability of at least two of the children getting the disease?
