Question

A special lottery is to be held to select the student who will live in the only deluxe room in a dormitory. There are 100 seniors, 150 juniors, and 200 sophomores who applied. Each senior's name is placed in the lottery 3 times; each junior's name, 2 times; and each sophomore's name, 1 time. What is the probability that a senior's name will be chosen?

Answer 1

Total senior names: 300
Total junior names: 300
Total sophmore names: 200

You want a senior's name to win, so it is 300/800 or 3/8 probability of that event happening.
