Yes.

A diagnstic test:
a person has the disease the test gives a positive result 99% of the
time
while an individual without the disease will show a positive result 2%
of the time

Let A be the event "test positive," and
B the "person really has disease."

Can I conclude the followings?

P(A | B) = 0.99, P(not A | B) = 0.01,
P(A | not B) = 0.02, P(not A | not B) = 0.98
