A bag contains 3 red, 4 blue, and 6 yellow marbles. One marble is selected
at a time, and once a marble is selected, it is NOT replaced. Find the
probability of choosing a blue, then red, then yellow. P(blue, red, yellow).
Here are my answers choices:
1/3
6/143
15/263
3/13

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
