You can put this solution on YOUR website! so they gave the choice of one cheese, one vegetable and one meat for $9.00. all oyu have to do is use the permutation formula to find the probabilities.
P(11,1).P(7,1).P(6,1)/P(24,3).You have a choice of 7 cheeses, 11 vegetables and 6 meats. so it will be 11 chose one, 7 chose one, and 6 chose one. and i got P(24,3), 24 by the ones they told you chose from that is 11+7+6=24 and i got 3 was 1+1+1=3.
so P(11,1).P(7,1).P(6,1)/P(24,3) and the formula for permutation is n!/(n-r)! or you can just plug it in your calculator.
=11.7.6/12144
=462/12144
=7/184
