Abag has 2 green marbles, 3 red marbles, and 3 yellow marbles. what is the probabilty that you pick a yellow marble, do not replace it, and pick another yellow marble?
3/28
1/28
9/56
1/8

Step-by-step explanation:

We will find probability of picking yellow in first try (denote as P(y1) )

and then find probability of picking yellow in 2nd try ( denote as P(y2) )

and then multiply both to get our answer.

Total number of marbles = 2 + 3 + 3 = 8 marbles

Of them, 3 are yellow, so

P(y1) = 3/8

Now, since WITHOUT replacement, we have taken a yellow, that means there are now 2 yellow and total will decrease by 1 as well, so total is 7, So

P(y2) = 2/7

Now,

P(y1 and y2) = 3/8 * 2/7 = 6/56 = 3/28

The first one is the correct answer,
