Percentiles in a Continous Random Variable distribution
The probability density function of x is:
f(x) = 4x(1-x^2) when x is a value between 0 and 1. (0 and 1 are included)
= 0 otherwise
What is the 75th percentile of this distribution?

By definition:
Find the value of a such that $\displaystyle \int_0^a 4x (1 - x^2) \, dx = 0.75$.
