Randomness

Here at the Valve Store(tm) we play a Safety Bingo game. Each week day a new number is “called” and the idea is that when each employee checks for the number he or she will be reminded to be safe.

Normally bingo numbers are chosen by computer or the old fashioned way by a ball dropping out of a barrel, but here, the company nurse, AKA: The Bingo Coordinator, uses a deck of cards.

I don’t know how long this has been going on, I just noticed it with the current game (only because it started on a Monday), but a random number from a particular row is always called on a particular day (on Monday it is B, Tuesday is I, Wednesday it’s an N, etc.)

So my question is, how less random is that than calling a number from all 75 at once?
