A jar has
12
12 marbles and
7
7 of them are green. You pull 2 marbles without replacement. What is the probability that both are green? Write your answer as a fraction. You do not need to simplify.
The probability of pulling a green marble on the first draw is 7/12.
Since we are not replacing the marbles, there are now 11 marbles left in the jar, with 6 green marbles.
The probability of pulling a green marble on the second draw is 6/11.
To find the probability that both marbles are green, we multiply the probabilities of each event:
(7/12) * (6/11) = 42/132
Therefore, the probability that both marbles are green is 42/132.
