Our end equation is something like this:

69! / 5! * 64!

This is, of course, shorthand, and means the same thing as:

(69! / 5!) / 64!

The end result of this equation is 11,238,513. But then we have to add the singular ball from the other drum which is drawn. There are twenty-six options here, so to calculate these odds, we take the answer to our previous equation and multiply it by 26.

11,238,513 * 26 = 292,201,338

What we discover by the end of this is that the odds of somebody winning the lottery are infinitesimally, disappointingly small. In fact, that’s 1 in 292,201,338 million. (In theoretical probability, barring any sort of savantism or clairvoyance.)
