Jesse has 4 pairs of black socks, 5 pairs of red socks, and 15 pairs of white socks in a dresser drawer. If he reaches in his drawer without looking, what is the probability that he will choose a pair of white socks? 62.5%
50%
70%
60%

62.5%

Step-by-step explanation:

You need to add all the socks to get the total amount of socks:

4 Black Pairs + 5 Red Pairs + 15 White Pair = 24 Total Pairs.

Next you need to find the probability of pulling a white pair so you divide the amount of white pairs to the total pairs of socks.

15 / 24 = 0.625 %

0.625 x 100 = 62.5%

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.
