Answer:
1/36
Step-by-step explanation:
The probability of rolling a number less than 6 or 6 itself on one die is 1/6. A pair of dice would be the combined probability 1/6*1/6 which is 1/36. So there's a 1/36 chance of having both dice roll numbers less than 6 or 6 itself.
6.4 - 2x - 6.63x = 610.5
subtract 6.4 from both sides
-2x -6.63x =604.1
collect like terms
-8.63x = 604.1
divide both sides by -8.63
x= -70
