Answer:
this answer for this question
y=833
<u>Answer:</u>
The correct answer option is 231 / 703
<u>Step-by-step explanation:</u>
We are given that a jar has 38 marbles, out of which 10 are red, 22 are black and 6 are green. Two marbles are drawn and the first marble is not returned when the second one is drawn.
We are to find the probability that both marbles are black.
1st draw: P (black) = 
2nd draw: P (black) = 
P (Both Black) =
= 231 / 703
So you need to find a number that goes into both of these numbers:
3 goes into both, so divide both by 3
27/3 = 9
42/3 = 14
so your answer is 9/14
