I think I'm doing this wrong, but I can't see where. Y is a random variable.

m'(t) = Expected Value (50 * e^(t*50) + 0.01 * Y * e^(t*0.01*Y))

m''(t) = Expected Value (50^2 * e^(t*50) + (0.01 * Y)^2 * e^(t*0.01*Y))

Are you trying to see if the second derivative is correct?

Yes, that's exactly it.

First factor out the constant, then use the chain rule.

Scheiße I can't use the formatting text correctly.
