Construct an Experimental, discrete probability table by rolling three six-sided dice and calculating the total. Perform 200 trials and record the results.

• Once all three lists are generated, add them to create the totals of the 200 trials.
• Then make a discrete random variable relative frequency histogram for this data, labeling the axes and scales clearly.
• Calculate the mean and standard deviation for the roll totals.

*Use these to define a normal probability distribution for the total on the roll of 3 dice.
