At the beginning of the semester, a professor tells
students that if they study for the tests, then there is a
55% chance they will get a B or higher on the tests. If
they do not study, there is a 20% chance that they will
get a B or higher on the tests. The professor knows
from prior surveys that 60% of students study for the
tests. The probabilities are displayed in the tree
diagram.
The professor informs the class that there will be a test
next week. What is the probability that a randomly
selected student studied if they do not pass the test
with a B or higher? 0.45 0.46 0.54 0.59
