I think I'm doing this correctly, but I want to make sure before I proceed, since for some reason I'm feeling unsure.

A group of people are each given a bag of marbles. Marbles come in three colors: red, blue and green. Some bags are empty, some bags have all marbles of one color, some have multiple colors.

4% of bags have all three colors.
5% have only green.
15% have both red and green.
23% have both red and blue.
55% have red.
25% have green.
43% have blue.

Note that unless I said 'only', then I don't mean 'only'.

Given those odds, what is the chance that a randomly chosen person has only blue marbles? What is the chance that a randomly chosen person's bag isn't empty? What is the chance that a randomly chosen person has exactly two types of marbles?

I've got some answers, but I'm still confused - it seems like there's not enough information in the stats, since it didn't say anything about the odds of green and blue, only blue or only red.

I actually saw this once. I programmed it in two dimensions to model the optical blurring of a two dimensional image coming through a small aperture. I FFT'd the pixel rows. I FFT'd the pixel columns. I did the convolution by matrix multiplying the transformed image with a two-dimensional gaussian probability distribution, and then I detransformed it to get the blurred image. And then I lost the algorithm, and now I'd like to have it again so that I can play with it. Does anybody know where it is?
