The probability of drawing a green marble is 8/20.
there are 20 marbles total and 8 of them are green.
Six hundred seven and four hundred nine one-thousandths.
We know a or b != 0
but a-b==0 so both are the same unknown number
b/a must = 1
so
a/b is equivalent to b/a as a/b=1 as well.
So the last answer choice.
Answer:
Both are correct. Either rule applied first will have the same result. Both rules will be used either way, and the order in which they are applied does not matter as long as they are applied correctly at each step.
