Science & Mathematics - 26 August 2006

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 watched a special one time that said the sun was shrinking then went out to professionals who said that your source was not correct and I could not remember the name of the source on television. So I think about this from time to time as it seems to represent the ozone arguments which go to extremes on both sides.

and just as many that believe just as firmly that they do. Are there any "agnostic" types that are unsure? It seems that you do, or you don't, but never any "I'm not sures" (except for me)
