Exercise 8.1 Bickel et al. [1975] report on gender biases for graduate admissions at UC Berkeley. This example is based on that case, but the numbers are fictional. There are two departments, which we will call dept#1 and dept#2 (so Dept is a random variable with values dept#1 and dept#2) which students can apply to. Assume students apply to one, but not both. Students have a gender (male or fe- male), and are either admitted or not. Consider the table of the percent of students in each category of Figure 8.33 (on the next page).

Exercise 8.1 Bickel et al. [1975] report on gender biases for graduate admissions
at UC Berkeley. This example is based on that case, but the numbers are fictional.
There are two departments, which we will call dept#1 and dept#2 (so Dept is
a random variable with values dept#1 and dept#2) which students can apply to.
Assume students apply to one, but not both. Students have a gender (male or fe-
male), and are either admitted or not. Consider the table of the percent of students
in each category of Figure 8.33 (on the next page).
In the semantics of possible worlds, we will treat the students as possible
worlds, each with the same measure.
(a) What is P(Admitted=true | Gender=male)?
What is P(Admitted=true | Gender=female)?
Which gender is more likely to be admitted?
