Then the black cards=12
Step-by-step explanation:
N of red=3
N of black=10

Answer:
2/13
Explanation:
The bag has 6 red, 3 green, 4 blue.
Total marbles = 13
Probability of getting <u>blue the first time</u> would be 4/13 because 4 of the 13 total marbles are blue
Because you're not putting back the first marble, the total would go down to 12, so the probability of getting <u>red the second time</u> would be 6/12 or 1/2
The probability that the first marble is blue and the second marble is red = (4/13)(6/12) = 2/13
I hope this answer your question.
