Statistics homework need help please

It does not look like a distribution problem to me...merely the probability of a joint event (like totalling the score on two dice)
Use a two dimensional sample space (with A outcomes across by B outcomes down) You are then merely counting squares for the joint event and dividing by the total number of squares(7x15).
or
a. multiply the probabilities for both white.
b. multiply the probabilities of (Dick white) x ( NOT Jane white)

Here are the basic scenarios.

Both Black draws = 6/7 * 14/15 = 4/5
Dick White, Jane Black = 1/15 * 6/7 = 2/35
Dick Black, Jane White = 1/7 * 14/15 = 2/15
Both White draws = 1/7 * 1/15 = 1/105

This is a recursive problem. If both are black, we replace the balls and draws again, getting the exact same probabilities, so let's look at Dick drawing white and Jane drawing black. The chance is the sum of the first draw probability (2/35), plus the second draw probability (4/5 * 2/35) plus the third draw probability (4/5)^2 * 2/35 ... This is a geometric series of the form

2/35 * (1 + 4/5 + (4/5)^ + (4/5)^3 + ... ) = (2/35) / (1 - 4/5) = 2/7.

Using the same technique, the probability of Dick drawing black and Jane drawing white is 2/3 and the probability of both drawing white is 1/21.

On the other hand , if you've had too much

See Spot Run Solution:

Jane has 6 chances of losing and 1 chance of a tie.
Dick has 14 chances of losing and 1 chance of a tie.
The cumulative probability is therefore:
1 chance in 21 of a tie = 1/21
14 chances in 21 of Jane winning = 2/3
6 chances in 21 of Dick winning = 2/7

I think you just made that up and it isn't a solution to the problem.

I agree. I suspect ekename is probably half in the bag with all the silliness that it/she/he spouts about everything in general and math in particular.

Engineer, do you like my solution or do you think it's a teensy bit
