    MHB Getting Nowhere with a Proof Question: Help Needed

    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...

    MHB Question: How do I calculate conditional probability in this scenario?

    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...

    MHB Find the General Expression for a Linear Transformation

    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. )

    MHB Question: How do I calculate conditional probability in this scenario?

    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...
