Answer:
2/15
Step-by-step explanation:
6 red marbles and 4 yellow marbles = 10 marbles
P ( 1st is yellow) = yellow marbles / total marbles
= 4/10 = 2/5
The marble is not replaced
6 red marbles and 3 yellow marbles = 9 marbles
P ( 2nd is red) = red marbles / total marbles
= 3/9 = 1/3
P ( yellow, red) = 2/5 * 1/3 = 2/15
