1. (a) A committee of 6 people is to be chosen at random in a Club which has a membership of 20 men and 30 women. What is the probability that 6 marks 6 marks 8 marks] (b) In a factory there are three machines which produce bolts. Machine A pro- duces 50% of the bolts and of these 2% are faulty. Machine B produces 20% of the bolts and of these 1.5% are faulty, and Machine C produces 30%...

A lot of 100 items contains k defective items. m items are chosen at random and tested. What is the probability that r items are found defective
(10 points) A lot of 100 items contains k defective items. M (Ms100) items are chosen at random and tested (a) (2 pts) How many different ways can we choose M items from 100 items in the lot? (b) (4 pts) How many different ways that among the M items chosen, m (msk) are found 1. defective? the M items chosen? probability that the lot is accepted? (c) (2 pts) Based on (a) and (b), what is the probability that...
If a permutation is chosen at random from the letters "AAABBBCCC", what is the probability that it begins with at least 2 A's? Round your answer to 6 decimal places as needed. Preview
A letter is chosen uniformly at random from {A, B, . . . , Z}. If that letter is one of the vowels (i.e. A, E, I, O or U) then a second letter is chosen uniformly at random from {A, B, . . . , Z}. Let L be the number of letters chosen and let V be the number of vowels chosen. (i) What is the expected value of L? (ii) What is the expected value of V?...
The probability that a circuit board produced by a particular manufacturer has a defect is 1%. You can assume that errors are independent, so the event that one circuit board has a defect is independent of whether a different circuit board has a defect. (d) Now suppose that the circuit boards are made in batches of two. Either both circuit boards in a batch have a defect or they are both free of defects. The probability that a batch has...
