Roll two dice 48 times and record the sum of the spots on the top faces as you roll. Then construct a probability distribution for your 48 sums. Using the probability distribution you constructed, find the mean number of spots. (If you don't have two dice, then cut out 6 pieces of paper with each being the same size and with #1,2,3,4,5,6 written on them. Place the pieces of paper in a hat or bowl. Pull out a number, then replace, pull out a number again and record the sum of the 2 numbers.) (c) Is the mean in (b) close to the mean in (a)? Explain why there is a difference in the two means or why they are the same.
