Three dice are tossed, one red, one blue, and one green. what outcomes make up the event a that the sum of the three faces showing equal 5

The outcome that makes up the event a that the sum of the three faces showing equal 5 is; P(E) = 1/36

Since there are three dices.

Let Red dice be R

Let Blue dice be B

Let Green Dice be G

      Now, for the sum of the three numbers on all dice to equal five, it means that no number out of the six possible numbers must be greater than 3.

Thus, P(R) = 3/6

Now, if P(R) = 3/6, it means that none of the other 2 dice can produce 3 or more as it will make the sum more than the required 5.

Thus; P(B) = 2/6

Now, if we now have P(R) and P(B) is gotten, it means P(Y) must be 1/6

Thus, the outcome that makes up the event a that the sum of the three faces showing equal 5 is P(E) = 3/6 × 2/6 × 1/6

P(E) = 1/36

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.
