For dinner at a restaurant, there are x +1 choices of appetizers, y main courses, and z +1 choices of dessert. How many total possible choices are there if you choose 1 appetizer, 1 main course, and 1 dessert for your meal?	Choose one.
A) xyz+xy+yz+y
B) xyz + xz
C) xy + z + 1
D) xyz + 1
E) xyz + 1/2
x appetizers,   y + 1 main courses,   z dessert   Required: 1 appetizer, 1 main course, and 1 dessert   Number of ways possible = yC1*(x+1)C1*(z+1)C1 {NC1 = N! / (N-1)!*1! = N}   Hence, number of ways = y(x+1)(z+1) = (xy + y)(z+1)=xyz+xy+yz+y   Correct Option: xyz+xy+yz+y
