1. The problem statement, all variables and given/known data 3. The attempt at a solution I know how to compute something like Pr(x<0.25) for example, but I'm unsure how to do it for an exact number like in question (ii). I attempted to integrate and then sub x=1/4 where neccisary, but to no avail! Part (iii) I really have no idea! Would be grateful is someone could explain these to me. Thanks!
