A special 20-sided die is constructed so that each face has one of the following numbers on it: 1, 2, 3, or 4. The table below gives the probability of each value (with one value missing).
when you add up all of the probabilities you want them to equal 1, first you need to find the missing probability (.2) then add the probability of 1 and 3 the odd numbers to get .6
