Events A1, A2 and A3 form a partiton of the sample space S with probabilities P(A1) = 0.3, P(A2) = 0.5, P(A3) = 0.2.

If E is an event in S with P(E|A1) = 0.1, P(E|A2) = 0.6, P(E|A3) = 0.8, compute

P(E) =

P(A1|E) =

P(A2|E) =

P(A3|E) =

Three runners competed in a race data were collected at each mile mark for each runner if the runner ran at a constant pace the data would be linear
