right.
At the start of the roll, the chance of hitting any number on the table is 1: 37...
But to say "this table will hit the same number on the first, second, fifth, and sixth rolls" starting now... those odds are 1: 50653.
Once x is defined, the chance for x to be hit on any subsequent roll is 1/37.... so for x (in this case, x = 3) to be hit on predefined rolls:
x (roll that defines x), then x w y z x x
The odds are:
1/1, then 1/37 1/1 1/1 1/1 1/37 1/37
Multiply them together, and you get 1:50653.
Been awhile since I've taken a probability class, so maybe I missed something, but understand I'm working from the perspective of the entire set of numbers... not an individual roll - which is always 1/37 on any number, as you said.
