There are 450 ways a person can order a two-course meal consisting of an appetizer and a main course according to the counting principle.
The fundamental of counting principle defines that if we have to choose one item from a group of M items and a second item from another group of N items, then the total number of two item choices is
M*N
Here we have been given that there are 15 appetizers and 30 main courses that is according to the fundamental of counting principle we have been given
M = 15 and N = 30
Thus the total number of two-course meal is = M*N
= 15*30
= 450
Hence there are 450 ways a person can order a two-course meal consisting of an appetizer and a main course.
