For dinner at a restaurant, there are x+ 1 choices of appetizers, y main courses, and z 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 the correct option:	A) x + y + z + 1	B) xyz + xz	C) xy + z + 1	D) xyz + 1	E) xyz + yz
x + 1 appetizers,   y main courses,   z dessert   Required: 1 appetizer, 1 main course, and 1 dessert   Number of ways possible = yC1*(x+1)C1*zC1 {NC1 = N! / (N-1)!*1! = N}   Hence, number of ways = y(x+1)z = xyz + yz   Correct Option: xyz + yz
<result>E</result>
