If you see question marks that's the negation

I'm stuck on this proof question: (¬(Q⇒¬P) ∧ ¬((Q∧¬R)⇒¬P )) ⇔ ¬(R ∨ (P ⇒¬Q)) I've tried to get rid of the negation and implications but I keep going in circles and I'm getting nowhere near to the equivalence required. I would appreciative if anyone can help me solve this because it's really...

I worked that out but is the last question 0.667 (3d.p), the reason I'm not sure about this last question is because the approximations at the bottom is different. And is the second to last question I think: $P(U|S)$ = (90,000/1,000,000) / (540,000/1,000,000) Only these two I'm not...

Thanks a lot

Answer to first q P(n|u) = 0.8 right? P(n|t) = 0.1 right ? and Second question answer is 0.05?

Can you see if answer to first question is (-r, 3s, 2t, u)? Or is it Idk how to use latex but it's one matrix (-r -2s+u) (3s+t+u) (2r+2t-4u) (. -s. )

I don't quite get this question, how is it done ?

i am trying to push myself and learn these furTher exercises in my maths i would any appreciate any comments and help. Question 1 what is probability u happens if n happens... P(U INTERSECTION N) / P(U)? Question 2 probability of U or S happening in the sample space of UDP or 52 byte size...
