    the denominator of you probability would be 33 since there are 33 people in all

    no, I'm sorry the definition is: probability= favorable outcomes/ possible outcomes

    total boys = 12 total girls=21 total children =12+21 =33 probability(a boy name is drawn) =total number of favourable events/total no. of events P=12/33 :)

    so the favorable outcomes are, probability times possible outcomes: \[\Large \frac{8}{{50}} \cdot 500 = ...?\]
