Hi finalepihpany,
it is true that you have only one choice out of three, not of four any longer.
However, it is not true that the probability of passing the overall exam increases by far.
This has to do with the binomial distribution, since the number of right answers it binomially distributed B(n, 0.33) and not B(n, 0.25) anymore. Try to think about it... ;-9
