From 10 men and 8 women in a pool of potential jurors, 12 people are chosen at random to constitute a jury. Suppose that you observe the number of men who are chose for the jury. Let A be the event that at least half of the 12 jurors are men and B be the event that at least half of the 8 women are on the jury.

(a) Determine the sample space of this random experiment.
(b) Find A B, A B, and A B? listing the outcomes for each of those three events.
(c) Are A and B mutually exclusive? (explain your answer) (d) Are A and B? mutually exclusive?(explain your answer)
(e) Are A? and B? mutually exclusive?(explain your answer

step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.

step-by-step explanation:

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
