As the probability of C should be the biggest one,the maximum is 1 Therefore,maxP(B)=1/2
and max P(A)=1/2*3/2=3/4that's what i got at the first place````but my dad said it should be one````because the maximum of a probability should be one````````````but thanks. i would like to hear more answers to this```OK, Don't worry~~You may tell your dad that you are the right one~~:-)yeah, he HAS to admitthat he's wrong!!!!
