Exercise 35

Critical thinking In an experiment, there are n independent trials. For each trail, there are three outcomes, A, B, and C. For each trail, the probability of outcome A is 0.40; the probability of outcome B is 0.50; and the probability of outcome C is 0.10. Suppose there are 10 trails.
(a) Can we use the binomial experiment model to determine the probability of four outcomes of type A, five of type B, and one of type C Explain.
(b) Can we use the binomial experiment model to determine the probability of four outcomes of type A and six outcomes that are not of type A Explain. What is the probability of success on each trial
