P(r) = 1-(2r2+2r+1)e-2r
i know that p(r) is just the derivative of P(r)
to find the median i would just integrate from o to r and set that equal to .5
but when you integrate youre just going back to P(r) from 0 to r
so i get
1-(2r2+2r+1)e-2r = .5
how would i go about solving this since i have the r's inside the parentheses and then the e raised to the -2r?
