A swim team of 150 has 75 advanced and 47 intermediate swimmers, with the rest novices. What is the probability that a member chosen at random is a novice?

1. The advanced and intermediate swimmers number 75 plus 47, which is 122 members. 2. The novices are the remainder, so there are 150 minus 122, which is 28 members. 3. Dividing 28 by the 150 members gives a probability of 28/150. 4. The count 40 belongs to the advanced swimmers who practise four times a week, not to the novices. _Source: OpenStax Introductory Business Statistics (CC BY 4.0), Ch 3 "Probability Topics", section 3.3 Two Basic Rules of Probability_
