    Arrow Curious about finding odds

    If 55 percent of a given population plays an instrument and 45 percent of the population watches movies and 8 percent of the population has blue eyes and only 3 percent of the population has won a gold medal in their lifetime... what are your odds of finding a blue-eyed, movie going, instrument playing, gold medalist? Please show math. I need a definite and sure answer. Thank you very much.

    Without further information, you can't. If you assume that these are all independent, that is, that blue eyed person is a likely to play an instrument as everyone else, that a person who watches movies is as likely to win a gold medal as everyone else, etc., then the answer is (0.55)(0.45(0.08)(0.03)=- 0.000594.

    what about Bayes theorem, would that work for this? Just a thought, I didn't answer because I am not sure but it is what I thought of to help.
