Thank you so much brother. I really needed this resource, very well explained. My teacher went through it quite quickly and I mean no offence to him that I didn't understand it all too well the first time round. But this has really cemented my understanding so thank you.

this is very good thanks, but you have confused me in your previous vid you said p(AuB) = p(A) + P(B) - p(AnB)          so your answer for p(PnH) should be 12-3 = 9/20 ??
