While Flying_Neko gave a great answer, it didn't answer your question. I don't know the number of chits in BM so I can only tell you how to calulate it yourself. Here's an example. Using a die there is a 1 in 6 chance to roll any number. To roll that same number it become 1 in 36 (6*6), to roll it roll it again it is 1 in 216 (6*6*6) Does this provide you with the tools to get your answer? Another way to phase it would be the number of chits raised to the power of the number of rolls. Number of chits^14. Big number.

Hope this helps.

Check out this ongoing League:
