I have a fair four-sided die, each of whose sides is an equilateral triangle. The faces are numbered 1, 2, 3 and 4. When I toss the die, the face of interest is the one on the bottom. If I toss the die twice, and add the numbers that are on the bottom-most side each time, the probability that the sum is three or four is Select one: O a. 2/7 O b. 2/16 O c. 3/16 O d. 1/7 O e. 5/16
