Please no written by hand solutions Printed circuit cards are placed in a functional test after being populated with semiconductor chips. A lot contains 140 cards, and 20 are selected without replacement for functional testing. a) If 20 cards are defective, what is the probability that at least 1 defective card is in the sample? b) If 5 cards are defective, what is the probability that at least 1 defective card appears in the sample? c) Calculate the mean and variance of the number of defectives in the sample when 5 cards are defective?

A quiz consists of 10 multiple choices questions with five choices A, B, C, D, and E. I did not study and randomly picked one answer for each question Find the probability that * I get at least one question correct * I pass the quiz. A passing grade is 60% or better * I receive an “A” on the quiz (i.e., 90% or better). * How many questions would you expect me to get correct? * Obtain the standard deviation of the number of correct answers.
