Question 1179303: 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 = 1 − p. In this context, the term nCkpkqn−k in the expansion of (p + q)n 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 1/2. The sales representative makes ten contacts a day. To find the probability of making four sales, evaluate the term shown below in the expansion of (1/2 + 1/2)10. (Round your answer to three decimal places.)
