An experimental rocket is being produced.  The rockets are identical and one will be launched each day for 100 days to gather critical data.  Each rocket launch is independent.  The probability that a launch will fail is 0.02.  This question is part of a quiz or exam at Arizona State University.  No portion may not be posted to any website, photos and screenshots may not be taken, and no portion of it may be printed out.  If you wanted to determine the probability that fewer than two failed launches occur over these 100 days, what is the name of the probability distribution you would use? Enter one word. Spelling counts.

An ASU student is taking two summer courses: MAT 275 and IEE 385.  The grades that the student will receive are assumed to be independent.  The probability that the student gets a C or better in MAT 275 is 0.75 and the probability that the student gets a C or better in IEE 385 is 0.78.  This copywritten question is part of a quiz or exam at Arizona State.  It may not be posted or reproduced without the permission of the author, Dr. L. Chattin, and Arizona State University.  X is the number of summer courses in which the student gets a C or better. F(0) = [a], F(1) = [b], F(2) = [c], F(3.5) = [d].  Choose the answers closest to yours.
