A manufacturer receives voltage regulators from the three different companies, A, B, and C. The proportions of the voltage regulators coming from the three companies are 65%, 27%, and 8%, respectively. If 90% of the voltage regulators are from A, 88% from B, and 70% of those from C meet the manufacturers expectations, what is the probability that a voltage regulator received by the manufacturer will meet its expectations? Use a tree diagram to help find the answer.© BrainMass Inc. brainmass.com March 22, 2019, 12:22 am ad1c9bdddf
