comment Flip a coin 6 times. What is probability of at least 4 heads?
= 42/64, or .65625 (Actually, the Pacers have won the first game, not the Heat. So the probability of the Heat winning the series is 1 - .65625 = .34375)

Just to make sure that I understand you: P(Win) is the probability of the Heat winning the series, and P(Win) = (22/64)x(.55/.45) = .420. Is this correct?

comment Flip a coin 6 times. What is probability of at least 4 heads?
Thanks very much. I get 11/32 as the answer to my coin flipping question. However, I don't understand why I should "lose the restriction that the odds are only as good as a coin-flip" for these NBA games. Or if I did put the probability of the Heat winning each remaining game at .55, how would I calculate the probability of the Heat winning the series?

Yes, I've heard of nCr combinations. 6C4 = 15.

Yes, I see. Thanks.

The point moving at a constant speed was not built into my question. The answer to my question remains "yes" even if the speed isn't constant. It could even stop repeatedly for finite lengths of time, no? Just wanting to touch all the bases....

Modifying question in response to Martin Argerami's comment.

comment In a family with two children, what are the chances, if one of the children is a girl, that both children are girls?
(continued) I assumed this because to interpret "one of my children is a girl" as meaning "exactly one of my children is a girl" would destroy the problem/puzzle in that the answer would be too obviously zero. Also, because I had first seen the question in a book about randomness and probability, I was already in math English mode.
