Karen has the cards below in a bag. Without looking, she pulls out a card. Karen is trying to determine whether each statement correctly describes the likelihood of an event based on the given cards. Help Karen to select True or False for each statement.

It is the probability of an event that is determined by the total number of outcomes.

P(getting a card from bag) = No. of outcomes

                                               Total number

So this is a true statement based on livelihood of an event.

Hope this helps!

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.
