At your dorm dining hall you met a fellow student who was recruiting volunteers to sign up to work at the local soup kitchen. You signed up and offered to help her recruit more volunteers tomorrow. As you are walking back to your room, you realize that you forgot to ask where to meet her. You are sure that it would be back in the dining hall or at the student union where she mentioned she sometimes goes to find volunteers.
To maximize the probability of finding her, what should you do? If you want to flip a coin, heads sends you to the dining hall and tails sends you to the student union.
