A red number cube and a white number cube are rolled. The faces of both cubes are numbered from 1 to 6. What is the probability of NOT rolling a 3 on the red number cube and rolling a number 3 OR LESS on the white number cube? Please select one answer.

The answer is 5/12 or 42%.

Explanation:

To get this, you have to see what the odds are for this to happen. What's the probability that it will not be a 3? 5/6. What about the probability of rolling 3 or less?. 1/2. Multiply the probabilities 5/6*1/2 and you get 5/12 or a 42% chance. Hope it helps!

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
