/* experiment 1

*

* Q. how many rolls does it take (on the average) to roll a seven or eleven?

*

* first write a loop to count the number of rolls needed to roll a seven or eleven

* For example if the rolls were: 2 8 3 5 12 11, it took 6 rolls to get an 11 (this time)

* then add code to repeat that test 1,000,000 times.

* return: the average (number of rolls needed) of all the tests

* hint: nested loops, use the sevenOrEleven instance method

* Question: what is the likelihood of rolling odd-valued doubles?

* should roll the dice 1,000,000 times and

* determine and return the percentage of rolls that are doubles

* with an odd die value. ( 1,1) or (3,3) or (5,5)
