Suppose a certain die has six sides, numbered from 1 to 6, but that the die is peculiar, in that it has the following properties: On any roll, the probability of rolling either a 1, a 4, or a 5 is 1/2, just as it is with an ordinary fair die. Moreover, the probability of rolling either a 5, a 3, or a 2 is again 1/2. However, the probability of rolling a 5 is 7/16, not 1/6  as one would expect of an ordinary fair die.

what is the probability of rolling a 6, a 3, or a 2 on a 6 sided fair die?
What is the probability of rolling anything but a 6?
