I edited the solutions and was the only proofreader for most of them, so there may be a few typos. Let me know if you see any and I'll get them fixed.
It's unlikely that I would be able to discuss any of the solutions, but I'm sure there are posters here who can help explain them. In fact, I owe Bama Gambler for pointing out in one of his posts that the normal approximation in #27 should use the continuity correction. With the numbers in that problem it doesn't matter, but it is theoretically right, so I incorporated it into our solution.
Several posters here solved #7 as the sum of an infinite series. That was fine. I didn't "steal" that one because I already had three solutions (one of which is likely too slow for exam conditions, but had some educational value, IMO, and is mathematically equivalent to that infinite series.)
