Hi everyone,

I don't know what happen, less than one month before the exam and I feel completely lost. I could do things really easily and now I cannot, maybe the stress or I don't know.. Do you h ave any advice or something, I do not want to fail my exam.

Also, if someone could help me with these 2 questions please.

If Pr (E ∩ F’) = 0.4 , Pr (E’∩ F’) = 0.05 and (E ∩ F) is denoted as x, given that Pr (F | E) = 1/5

i. Find Pr (E ∪ F)

ii. Find Pr (E | F’)

Thank you
