- Evaluating Cnr In Exercises 49-52, evaluate Cnr using the formula from this section. C99arrow_forwardProbability In Exercises 77-80, consider n independent trials of an experiment in which each trial has two possible outcomes: “success” or “failure.” The probability of a success on each trial is p, and the probability of a failure is q=1p. In this context, the term Cnkpkqnk in the expansion of p+qn gives the probability of k successes in the n trials of the experiment. The probability of a sales representative making a sale with any one customer is 13. The sales representative makes eight contacts a day. To find the probability of making four sales, evaluate the term C84134234 in the expansion of 13+238.arrow_forwardEvaluating Pnr In Exercises 31-34, evaluate Pnr. P52arrow_forward
