AT THE SPEED OF LIGHT

>>6021057

ok bitch you know how when you move an object, the whole thing doesn;t move at once, you actually compress the first side you touch and it sends a wave through the object and eventually slice by slice the whole thing moves? Like, yeah...


Anyways that takes place at the speed of light. If you were traveling the speed of light, those compressions would not be able to "make it all the way" before being compressed further, which would cause the object to implode into a photon which would travel up your butt

offered by statistics dept, if that's what you meant.

>>5920656

a mathy statistics class

corresponding books are khuri, advanced calculas with applications in statistics, and hogg, mathematical statistics

no more pls ;_;

That does ABSOLUTELY NOT follow the def of martingale.

You are dealing with the ACTUAL Xn-1, which is, in general, not equal to E(Xn-1).

If E(Xn-1) = Xn-1 (the expectation is ALWAYS the actual outcome) then you'd be correct. But that is, I hope you see why, totally ridiculous on a few different levels.

isn't that NOT the definition of a martingale?

Xn is a martingale if E(Xn) = Xn-1... Just off my memory.. What you wrote is not the same..

Oh however the best approximation for this sum is 1/2

hey faggots

if the limit of the nth term does not approach 0, the sum of the partials does not exist. (ie series does not converge)

lim (-1)^n as n->inf does not = 0

op pls ;_;

nvm, nah I guess not.

But you can't make a function such that the limit is "aleph one" though right? Due to continuum hypothesis? I'm guessing this is an issue of interpretation and why you cannot describe the limit of some function to be an aleph number...

>>5824048

alephs only work for cardinalities?

lim[f(x)->0, g(x)->0]f(x)^g(x) is indeterminate. It can equal ANY value depending on the function.

expected number of pockets in total for the 23 students?

1/8*(0+1+2+4+5+6+7+8)*23

assuming that the probability of a student having i pockets = probability of having j pockets

Yeah I got another year left and i'm sort of just realizing now that the university doesn't actually help you get a job set up. You need to actually go do that yourself....

logic, rationality, metaphysics.

So producing a line of length .5 (which has a probability of .5) would be making 4 lines in the pattern of a square, which would have area .25. So shouldn't the answer for question 2 also be .5?
