A bag has 4 green marbles, 3 red marbles, and 3 yellow marbles. What is the probability that you pick a green marble, do not replace it, and pick a red marble?

Answer 1

On the first selection the probability of green is
\[\frac{4}{10}\]
On the second selection, having picked green on the first, the probability of red is
\[\frac{3}{9}\]
The probability of green then red is
\[\frac{4}{10} \times\frac{3}{9}=you\ can\ calculate\]
