Asked by Stephanie

Suppose there are 2 black, 3 white, and 5 red marbles in an urn. You reach in and
randomly select 3 marbles without replacement. And let X be the number of black marbles.
Find the probability table for X.
Answered by PsyDAG
Are you for the probability of selecting 3 black marbles? Since there are only two, probability is zero.
