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?

A. 4/11
B. 7/11
C. 9/11
D. 2/11

The correct answer is D. 2/11.

Step-by-step explanation:

To determine 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, the following calculation should be performed:

6 + 1 = 7

6 + 2 = 8

2/11 = X

Therefore, 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, is 2/11.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
