- Conditional probability If 40 of the population have completed college, and 85 of college graduates are registered to vote, what percent of the population are both college graduates and registered voters?arrow_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_forwardRefer to the spinner in Exercises 21-22 21—22 Refer to the spinner shown in the figure. find the probability of given event. Find the probability that the spinner has stopped on a number divisible by 3, given that it has stopped on blue.arrow_forward
