What is the probability of rolling a number less than or equal to 8 with the sum of two dice, given that at least one of the dice must show a 6?

4/11

Step-by-step explanation:

The sample space is (6,1),(6,2),(6,3),(6,4),(6,5)(2,6),(1,6),(3,6)(4,6),(5,6),(6,6). The Favorable outcome is (6,1),(6,2),(2,6) and(1,6). The probability is 4/11=4/11

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.
