Probability QuestionSix boys and twelve girls are in a senior class.Half the boys and 25% of the girls wear glasses.What is the chosen probability that a student chosen randomly is a boy,wears glasses,or both? I know the answer is 50%, but could someone could explain to me clearly how you get that answer? Thanks! The best thing about life is you don't know what to expect #2 20121124 13:19:58
Re: Probability QuestionProbability that the chosen one is a boy = Probability that the chosen one wears glasses = Probability that the chosen one is both a boy and wears glasses = (Probability of being a boy) * (Probability of a boy to wear glasses) = Last edited by Agnishom (20121124 13:22:47) 'And fun?
