[Maxima-discuss] "distrib" package

[Henry B. <hb...@pi...>]

I am just starting to play with the "distrib" package, and it looks to be very cool!

I'm extremely rusty on my probability, so I'd like to ask an extremely simple question:

Suppose I take 8 samples from normal distribution A and 8 samples from normal distribution B, each with its own mean and variance.

What is the probability that the sum of the 8 A-samples will exceed the sum of the 8 B-samples ?

Of course, "8" might also be some other number, like 5.

Thanks for any help.
