It is known that 35% of all candidates fail the first attempt to pass the test for a receipt for a driver's license in a particular city. For a random sample of five candidates taking the test for the first time: a. What is the probability that all of them will fail? b. What is the probability that most of them will pass (3 or more)?
Homework Answers
Here p=0.35 is same for all, n=5 is constant, events are independent and only two outcomes
Hence all the properties of binomial are satisfied
We will use binomial excel formula to find required probability
a.

5.45The Quinte Corporation manufactures parts for electronic consumer products. One contract calls for 95% of all parts to pass a certain test. When shipping a lot of 2500 or more parts, the Quinte Corporation adopts the following plan. Select a random sample of 35 parts from the shipment and determine how many pass the test. If 4 or more parts fail the test, the lot is considered to be unacceptable. If 0 or 1 parts fail, the lot is approved...
