Question

Which is more likely to occur (i.e. has a higher probability):
a. Rolling a 2 or higher on a single 6 sided die
b. Rolling a 3 or higher on a single 6 sided die, if you can re-roll the die if
you fail the first time

Answer 1

I think it is B. You have a 5 out of 6 chance on A but on B you have 4 out of 6 chance times 2. I'm not positive though.
