1. The table below shows the number of students that made honor roll last quarter. If a student is chosen at random, find each probability. Give your answers as fractions in simplest form.
Honor Roll
Yes No
9th Grade

a) P(honor roll | 11th grader)
b) P(9th grader | not honor roll)

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
