Suppose that for adults in a certain population 40% are male, 38% smoke, and 12% are female smokers. What is the probability that a randomly chosen adult smoker is a male? The Answer is apparently 0.6842 I have no idea how!

Thanks! I have a few more questions though. Can't I just take the derivative of the whole function and plug the values of t back in? How would I analyze this quatitatively and qualitatively? Also I was playing around with the graph in excel and putting the function in a cubic or 4th degree...

I chose to do a quad regression because it fits the data better. I know this is weird but i don't know why that worked out. Anyways, how would i generate the velocity from position? I was thinking of finding the derivative at each point. I'm not sure if that's correct though.
