Answer:
1/45
Step-by-step explanation:
There are 10 marbles
P ( yellow) = yellow marbles / total = 2/10 = 1/5
We do not replace the marble
There are 9 marbles, 1 of which is yellow
P ( yellow) = yellow marbles / total = 1/9
P ( yellow, no replacement, yellow) = 1/5 * 1/9 = 1/45
Answer:
x = 15

-2 1/2 / 6 would be -5/12, just turn - 2 1/2 into a decimal and divide by 6 :)
