A die (six faces) has the number 1 painted on three of its faces, the number 2 painted on two of its faces, and the number 3 painted on one face. Assume that each face is equally likely to come up.
a. Find a sample space for this experiment.
b. Find P(odd number).
c. If the die were loaded so that the face with the 3 on it were twice as likely to come up as each of the other five faces, would this change the sample space? Explain.
d. If the die were loaded so that the face with the 3 on it were twice as likely to come up as each of the other five faces, would this change the value of P(odd number)? Explain.
(a) {1, 2, 3}
(b) P(odd number) = P(1) + P(3) = 3?6 + 1?6 = 2?3
(c) No, the set of possible outcomes is still {1, 2, 3}.
(d) Yes, a list of equally likely outcomes is then {1, 1, 1, 2, 2, 3, 3}, so P(odd) = P(1) + P(3) = 3?7 + 2?7 = 5?7.
