Introductory combination problems like if you have 5 friends and can pick 2 of them to join you on a boat ride how many different groups of friends could you take with you. If we want to figure out how many combinations we have we just create all the permutations and divide by all the redundancies. There are 1365 different committees.
The five white balls have possible numbers ranging between 1 and 70 while the Mega Ball can be between 1 and 25.
There are 496 combinations without repetition. There are 10 balls in a bag numbered from 1 to 10. In our case we get 336 permutations from above and we divide by the 6 redundancies for each permutation and get 3366 56.
