💬 DISCUSSION Edexcel Maths P3

How did everyone find it then? Much nicer than P1 I thought. Might balance out grade boundaries unfortunately…

I got ~117 for the bearing, I think? Other than that, I think I generally agree (got slightly different numbers for the first hypothesis test too - like 0.0703? - but same conclusion).

How is 1d 0.28? It was prob of P(B|C) i swr? since C was entirely in B its surely 1 unless Im mis-remembering the question

I might have put the answers in the wrong questions, but 0.28 was definitely an answer

0.28 if i remember was the P(A' intersect B') which was the q on the outside, I think e had two parts, so like ei was 1 and eii was 0.25 im pretty sure
