will has two number cubes. what is the probability that the sum of what he roles will be 9
There are 36 possible outcomes when rolling two number cubes. This is because there are 6 possible outcomes on the first cube and 6 possible outcomes on the second cube (6 x 6 = 36). To find the probability of rolling a sum of 9, we need to count the number of outcomes where the sum is 9.
There are four outcomes where the sum is 9: (3,6), (4,5), (5,4), and (6,3). Therefore, the probability of rolling a sum of 9 is:
4/36 = 1/9
So the probability of rolling a sum of 9 is 1/9.
