Determine whether the following individual events are overlapping or non-overlapping. Then find the probability of the combined event. Getting a sum of either 4,8, or 11 on a roll of two die

They are overlapping. As a hint, think about the number of ways you can get those numbers, (for example 1 and 3, 3 and 1, and 2 and 2 for the 4), add those together, and than take all the possibilities and put it below and divide.

b.-4 units

all you   do is count how many times you move

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
