Friday Puzzler -- Probability redo

I deleted yesterday's puzzle, since I miss-stated it. Here's how it should have read:

Adam has four fair coins, and Beth has three fair coins. They toss all their coins. What is the probability that Adam will throw more heads than Beth?

Same as if Beth had 99 and Adam had 100.

Sorry for the initial miss-statement of the puzzle, which was merely a combinatorics question with no "aha" value.
