There are 11 widgets in box. 4 of them are defective and 7 of them are non-defective. Five widgets from the box are selected at random. a) What is the probability that exactly 2 parts will be defective, assuming no replacement after each selection? b) What is the probability that 1 sample widget selected will be defective, assuming no replacement after each selection?
A box contains 30 parts, of which 5 are defective and 25 are non-defective. If two parts are selected without replacement a.Construct a tree diagram with a listing of all the outcomes and probabilities: b.P(exactly one non-defective part) include both fractional and decimal answers. c.P( at least one defective) d.P( neither is defective)
A shipment of 40 parts contains 12 defective parts. Suppose 3 parts are selected at random, without replacement, from the shipment. What is the probability that exactly 2 parts are not defective?
Suppose a packing box contains 24 smartphones, of which two phones are defective. If, while setting up a store display, a salesclerk selects 10 smartphones at random from the box without replacement, what is the probability that both defective smartphones will be selected and put on display?

A shipment of 60 parts contains 9 defective parts. Suppose 3 parts are selected at random, without replacement, from the shipment. What is the probability that at most one part is not defective? Options: 0.9439 0.0887 0.0561 0.0296
7) A lot of 100 semiconductor chips contains 20 that are defective. Two chips are selected at random, without replacement, from the lot. (a) What is the probability that the first one selected is defective? (b) What is the probability that the second one selected is defective given that the first one was defective? (c) What is the probability that both are defective?
question: With probability = .25 , two switches are selected without replacement from box A, & with probability = .75 , two switches are selected without replacement from box B. box A contains 4 defective switches & 6 good switches (prob = .) box B contains 8 defective switches & 2 good switches (prob = .) Determine the probability that the 2nd chosen switch is defective, given that the 1st chosen switch is defective.
1) A flashlight has 6 batteries, 2 of which are defective. a) If 2 are selected at random without replacement, find the probability that both are defective. b) If 2 are selected at random with replacement, find the probability that both are defective. 2) How many different ways can an instructor select 4 textbooks from a possible 17?
