Looks like you have not posted the complete question. It says 0 elsewhere, implying there was more information given somewhere.
find the p(y<3.2) of the probability density function below
for 2<y<4
0 elsewhere
tried to solve the problem above by at 0<y<3.2 as boundary, but got a value greater then 1 which i think is not possible. how should i
had gone about it? thanks
