Work out the probability that the two marbles taken from the bag are the same color. Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles.

B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3. P blue then black 2 5 x 4 15 8 75. P both red frac binom22. If replacement is not allowed what is the probability that the second marble drawn will be red.
