In a maths paper there are 3 sections `A,B& C.` Section A is compulsory. Out of sections `B & C` a student has to attempt any one. Passing in the paper means passing in `A` & passing in `B` or `C`. The probability of the student passing in `A, B & C` are `p,q` & `1/2` respectively. If the probability that the student is successful is `1/2` then `:`
