Step-by-step explanation:
There is 5 blue marbles, 2 black marbles, and 3 red marbles. In other words, there is a total of 10 marbles.

There are only 3 red marbles out of the 10 total marbles. Therefore, the probability of drawing a red marble is 3/10 or 30%.
answer:
m^8 n^6
explanation:
m^5 and m^-3 should be subtracted so 5 - (-3) = 8
and n^2 and n^-4 should subtracted as well so 2 - (-4) = 6
