Document Summary

If this ball is red, what is the conditional probability that the other ball in this box is also red: in answering a question on a multiple-choice test, a student either knows the answer or guesses. Let p be the probability that the student knows the answer, and 1 p the probability that the student guesses the answer. Assume that a student who guesses the answer will be correct with probability 1 m, where m is the number of multiple-choice alternatives. What is the conditional probability that a student knew the answer given that the student answered it correctly: suppose p (a) = 3. Find the range of p (a b): a box contains r red balls and b blue balls. In each turn a ball is chosen, its color is noted, and it is returned to the box with d more balls with the same color.
