What This Question Tests
This question involves calculating the probability of an event (getting a 2 on a die roll) occurring on an even number of throws, which can be solved using geometric probability and sum of an infinite geometric series.
Concepts Tested
Formulas Used
P(success on nth trial) = (1-p)^(n-1) * p
