+4 Tria had one each of five different-shaped number solids having 4, 6, 8, 12, and 20 sides.
She rolled two at a time and found probabilities for the sum of the numbers that came up.
She recorded the probabilities in the first column of the table. When it came time to fill in the
second column, she had forgotten which number solids she had used. Figure out which
number of solids she must have used and explain your thinking. The first one has been done.
Probabilities in the first column:
The probability of a 3 is 2/80 or 1/40
The probability of a 3 is 1/80
The probability of a 4 is less than the probability of a 5
