Question

There are 35 athletes in a grade 10 gym class. 27 students play hockey and 10 play golf. what is the probability that a student chosen at random will play golf only?

Answer 1

Let's assume all students are athletes otherwise we're underdetermined.

`37` slots for `35` athletes means `2` must play both, so `8` play golf only, for a probability of

`8/35`
