Px(X) = M exp(- 2 |x|) + N exp(- 3 |x|) is the probability density function for the real random variable X, over the entire x axis. M and N are both positive real numbers. The equation relating M and N is
M + N = 1
M + N = 3
Answer: Option
Explanation:
Using property of probability density of 
Pxdx = 1
[M exp(- 2 |x|) + N exp(- 3|x|)]dx
