Suppose a six-sided die is “loaded” so that any particular even-numbered face is twice as likely to be observed as any particular odd-numbered face. A) What are the probabilities of the six simple events? B) What is the probability that the number showing is an odd number? At most 3: C) Now suppose the die is loaded so that the probability of any particular simple event is proportional to the number showing on the corresponding upturned face; that is, P(1) = p; P(2) = 2p; … List the events. Calculate the probabilities in part b for this die. 1/3 4/9 P p p p p p 1/ / / / / /21 Calculate the probabilities from part B above for this die. 3/7 2/7
