SAT question 16cea46c (Probability And Conditional Probability)

Question

A total of 25 men registered for singing lessons. The frequency table shows how many of these singers have certain voice types. If one of these singers is selected at random, what is the probability he is a baritone?

College Board · Accepted Answer

The correct answer is B. Choice B is correct. This probability is calculated by dividing the number of baritone singers by the total number of men registered for singing lessons. It's given that a total of 25 men registered for singing lessons and that there are 10 baritones. Therefore, the probability of selecting a baritone from this group at random is (10)/(25) , which is equivalent to 0.40 .
