Dear All, I have a probability question that may seem easy (and, quite possibly is) but is causing me some brain ache. I have two groups. I am measuring calcium on them and they form two normal distributions. Now if I take a calcium reading at random from the population, what is the probability that the person is from group A? The person can only be in group A or group B, but not both as the groups are mutually exclusive. Im guessing if this involves likelihood ratios that I can extend this to the bivariate normal distribution which is my eventual aim.
