(1 point) Rework problem 22 from section 2.4 of your text, involving the assignment of tasks to student union board members. Assume that there are 16 board members: 12 females, and 4 males including Carl. There are 3 tasks to be assigned. Note that assigning the same people different tasks constitutes a different assignment. (1) Find the probability that both males and females are given a task. (2) Find the probability that Carl and at least one female are given...
Rework problem 18 from section 4.3 of your text, involving the expected number of putts made in a golf tournament. Assume that the golfer makes 70 percent of putts when they are less than 10 feet and 30 percent of putts when they are 10 feet or longer. The golfer takes 27 putts from less than 10 feet and 74 putts from 10 feet or longer during the tournament. How many putts can the golfer expect to make during the...
3) We roll 2 fair dice. a) Find the probabilities of getting each possible sum (i.e. find Pr(2), Pr(3), . Pr(12) ) b) Find the probability of getting a sum of 3 or 4 (i.e.find Pr(3 or 4)) c) Find the probability we roll doubles (both dice show the same value). d) Find the probability that we roll a sum of 8 or doubles (both dice show the same value). e) Is it more likely that we get a sum...
(1 point) Rework problem 18 from section 3.3 of your text, involving filling in missing probabilities on a tree diagram. Construct a copy of figure 3.11 in your text, where the first outcome is one of (A,B,C) and the second outcome in each case is one of (1,2,3) (only 1 or 2 in the case of outcome C). Use the following probabilities instead of those given in your text: 12 12 12 12 Find the following missing probabilities (1) Pr[A...

MATLAB problem Imagine we have three types of coins in a bag: Fair Coin (FC) with Pr(Head) = Pr(Tail) = 0.5; Head-heavy Coin (HC) with Pr(Head) = 0.4; and Tail-heavy Coin (TC) with Pr(Head) = 0.6. A coin is randomly picked out of the bag. Write a MATLAB code that can estimate the type of this coin The result graph should look like this: Flipping a Fair Coin for 400 Times Fiping a Coin (1 for Head and 0 for...
Rework problem 21 from section 2.4 of your text, involving the assignment of tasks to student union board members. Assume that there are 11 board members: 7 females, and 4 males including Tom. There are 2 tasks to be assigned randomly, including that of reserving a room for meetings. There is at most one task per person. (1) Find the probability that Tom is given a task. equation editorEquation Editor (2) Find the probability that Tom is given the task...
