I’m sitting an exam with 69 study units. I only have time to study 25. The exam consists of 5 questions relating to different study units. I only have to answer 1. What are the chances one of the units I have studied will come up.

I assume that number greater than or equal to 1 is a good situtation. P(x ≥1) is (1 - P(0)).
P(0) = 44C5/69C5 where 44 is the unstudied pool and 69 is the total pool from which 5 questions are chosen.
