Answer:
1/10
Step-by-step explanation:
four green marbles, three red marbles, and three yellow marbles
Original total number of marbles: 4 + 3 + 3 = 10
First pick
Picking a red marble. There are 3 red marbles.
p(red) = 3/10
Second pick
Since the red marble picked is not replaced, now the total is 9 marbles.
Picking a yellow marble. There are 3 yellow marbles.
p(yellow) = 3/9 = 1/3
The probability of both events is the product of the individual probabilities.
p(red then yellow) = 3/10 * 1/3 = 1/10
