# Calculating probabilities

For people with a certain disease, the length of time Y spent in remission is described by the following pdf

f(y) = (1/9)y^2, 0<=y<=3

where Y is measured in years.

What is the probability that a patient's remission lasts longer than 1 year?

#### Solution Preview

So, we have the pdf, (1/9) y^2, 0<=y<=3. To calculate probabilities from a pdf, we integrate. We are looking for the probability that remission lasts longer ...
