At a large university, 15% of students are left-handed. A psychology professor selects a random sample of 10 students and records L = the number of left-handed students in the sample.What kind of result could be recorded for each trial?

Each trial is one random sample of 10 students, and L counts how many of those 10 are left-handed. The count can be any whole number from 0 (none are left-handed) to 10 (all are left-handed). Therefore, the possible results are 0 through 10 left-handed students, as in choice A.
