hello!
I'm trying to understand the following property:
Let X and Y be independent random variables z: = X + Y. Then

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:
