Answer:
7/12
Step-by-step explanation:
1, 2, 3, 4, 5, 6, and 7, are all possible rolls less than 8. that's seven combos.
Seven out of twelve. That's 7/12. So the probability of rolling a number less than 8 on a 12 sided die is 7/12.
30
multiply then divide then multiply again
64
The volume of rectangular prisms is measured by l*w*h
And by counting the units of the length, width, and height are all 4 units long.
So take the numbers and plot them into the formula
4*4*4 = V
16 * 4 = V
64 = V
The prism is 64 cubic units.
M = {2, 3, 5, 7} (and possibly includes 11 if "between x and y" means to include both x and y)
N = {1, 2, 3, 4, 6, 12}
Then
M U N = {1, 2, 3, 4, 5, 6, 7, 12}
(or possibly {1, 2, 3, 4, 5, 6, 7, 11, 12})
M ∩ N = {2, 3}
