You roll a number cube once.
what is the theoretical probability that you roll a 3 or 4?

3 = 1/6 chance 4 = 1/6 chance

Step-by-step explanation:

BECAUSE there are 6 numbers on a number cube and there is no ganruntee that it will land on 4 or 3 so its a 1/6 chance that it will land on them.

1/6

Step-by-step explanation:

A dice (Number cube in this case) has six sides, in only which one side is three and one side is 4.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
