Let X have the p.d.f. f (x) = c * e^(Abs(x)) for -1<= x < 1 (please note the absolute value marks.

I determined c to be 1/(2e-2)

but how do you calculate the median of X. I believe it has something to do with the 50th percentile but I'm not sure how to make that calculation. Thank you for your time.
