Eduardo has a red 6-sided number cube and a blue 6-sided number cube. the faces of the cubes are numbered 1 through 6. eduardo rolls both cubes at the same time. the random variable x is the number on the red cube minus the number on the blue cube. what is p(−2≤x≤1)? enter your answer, in simplest fraction form, in the box.

5/9

Step-by-step explanation: Just took the test

P(−2≤X≤1) = 5/9.

Step-by-step explanation:

Given:

P(-2≤X≤1) and he random variable X is the number on the red cube minus the number on the blue cube

x = -2. -1. 0 and 1

Let's take first number as in the red cube and the second number is in blue cube.

We get x = -2 for the following outcomes

(1, 3), (2, 4), (3, 5), and (4, 6).  which is 4 favorable outcomes.

We get x = -1,  for the following outcomes:

(1, 2), (2, 3), (3, 4), (4, 5), and (5, 6).  which is 5 favorable outcomes

We get x = 0, when (1, 1) (2, 2)(3, 3)(4, 4) (5, 5),(6, 6) which is 6

We get x = 1, when (2, 1), (3, 2) (4, 3) (5, 4) (6, 5), which is 5.

The number of favorable outcomes=  4 + 5 + 6 + 5 = 20

The number of possible outcomes = 36 (when we toss the two dices, the possible number of outcomes is 36)

The required probability  P(−2≤X≤1) = The total number of favorable outcomes / the total number of possible outcomes

= 20/36

P(−2≤X≤1) = 5/9.

Hope this will helpful.

Thank you.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
