    Can you please explain why I should not put a positive infinity upper boundary (10^99) when finding the exponential prob. distribution? Since doing so will give me 0 as the probability. And what is the ideal value of upper boundary to put? Thanks in advance!

    Well I think they're just saying that if you use a big enough value then you're going to get 0 - - e^-3 = 0.0498 because e^-(big enough number) is practically zero. I don't see why you have to put a number in a calculator to see this though.

    In any case you could just do 1-the integral from 0 to 10.
