An officer is always late to the office and arrives within the grace period of ten minutes after the start. Let X b the time that elapses between the start and the time the officer signs in with a probability density function.
$$f(x)=begin{cases} kx^2&:& 0leqslant xleqslant 10\0 &:& text{otherwise}end{cases}$$
where k > 0 is a constant.
Compute the value of K.
Find the probability that the he arrives less than 3 minutes after the start of the office.

Straightforward enough.
$1 = kint_0^{10}x^2dx$. You should be able to solve for k knowing this. The second part is the value of $kint_0^{3}x^2dx$ using $k$ from the first part.
