Aspinner is numbered from 1 through 10 with each number equally likely to occur. what is the probability of obtaining a number less than 2 or greater than 7 in a single spin?

Step-by-step explanation:

There are 10 total outcomes [numbers from 1 to 10]

What are the numbers that are LESS THAN 2 or GREATER THAN 7?

They are 1, 8, 9, and 10.

That's a total of 4 numbers. Also, total numbers is 10. Hence the probability of obtaining numbers that are less than 2 or greater than 7 is:

Simplifying gives us a probability of  

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.
