comment Expectation of an event
@Gortaur: There are only 1001 states. See the linked answer. Looks like I made a mistake in my code; the answer is 2861...

comment Expectation of an event
Anyway, the answer is 2055.23... Looking forward to seeing if anyone can do this analytically.

@Gortaur: it means that you $j_1$ could equal $j_2$, etc.

comment Expectation of an event
This is easy to solve (exactly) with dynamic programming, but I'm not sure how to do it analytically.

comment Convolution of probability densities. Having trouble integrating over vector
thanks! B is the multinomial beta function, which I think normalizes the distribution correctly. the domain of integration is such that the arguments passed to f are always negative (l - x <= l - l = 0).

FYI the mean is a synonym for expected value
