hello! I'm trying to understand the following property: Let X and Y be independent random variables z: = X + Y. Then http://imageshack.us/a/img268/9228/71pe.png where fZ (z) is the probability mass function for a discrete random variable defined as follows...

Thanks! You were right ;)

Hi Everyone! I'm with Conditional Probability and I don't understan this theorem. Theorem: If http://imageshack.us/a/img28/1349/1qg.png then http://imageshack.us/a/img209/8829/aor.png Proof: All the conditional probabilities are well defined, since http://imageshack.us/a/img197/8938/4xp.png...

Professor Roberto has to take an oral examination. The grading scale is as follows: 5: = best and 1: = worst. At most he only gives the note 4. Each student under review is questioned if he is a Lakers fan. The student's grade is based on his answer (is a fan / not a fan) and on the language in...

Hi! I have to do this exercise: Define a finite probabilistic Space (Ω; Pr[ ]) and 2 events A,B⊆ Ω and Pr[A] ≠ Pr[B] so that we can verify that Pr[A∩B]>=9*Pr[A]*Pr[B] > 0. (1) ___________________________________________ I've been trying it but i have reached this conclusion: If Pr[A]>0...

Hi I've found this exercise but I do not understand the solution: _________________________________________________________________ In a party c candies are given randomly to n kids. ¿Which is the probablility that my nephew doesn't receive any candy? We supose the candies and the kids are...
