How to find the probability of a continous random variable at a point using its cumulative distribution function? Its Probability density function here is: Question : How can I calculate the following possibility: $\int^2_0 f(x) =[−c(x−2)^4/4]_0^2 = 4c =1$, So the Cumulative distribution function should be : $F(x) = -0.25 * (x-2)^4/4$, Now I know that $P(1 < X < 4) = F(4) - F(1)$, but I cannot get the given solution ($0.06$). How do I include a JavaScript file in another JavaScript file? Since $X$ takes values in $[0,2]$ we have $X <4$ with probability $1$. her the density is $0$ for $x<0$. Thanks for your help!
