Military radar and missile detection systems are designed to warn a country of an enemy attack. A reliability question is whether a detection system will be able to identify an attack and issue a warning. Assume that a particular detection system has a 0.90 probability of detecting a missile attack. If three detection systems are installed in the same area and operate independently, what is the probability that I will save my life?

Consider a multiple-choice examination with 50 questions. Each question has four possible answers. Assume that a student who has done the homework and attended lectures has a 75% probability of answering any question correctly. A student who answers 35 to 39 questions correctly will receive a grade of C. What is the probability that a student who has done their homework and attended lectures will obtain a grade of C on this multiple-choice examination?

Axline Computers manufactures personal computers at two plants, one in Texas and the other in Hawaii. The Texas plant has 40 employees; the Hawaii plant has 20. A random sample of 10 employees is to be asked to fill out a benefits questionnaire. What is the probability that none of the employees in the sample work at the plant in Hawaii?

Consider a multiple-choice examination with 50 questions. Each question has four possible answers.

A student who answers 35 to 39 questions correctly will receive a grade of C. What is the probability that a student who has done their homework and attended lectures will NOT obtain a grade of C on this multiple-choice? examination?
