By permutation without repetition, there are 524160 possible different special pizzas.
The possible special pizzas can be calculated with permutation without repetition. The formula of permutation without repetition can be written as
P = n! / (n - k)!
where P is all of the possible combinations, n is the number of objects or elements, and k is how many numbers should be chosen.
From the question above, we know that :
n = 16
k = 5
By substituting the parameters, we can determine all of the possible different pizzas
P = n! / (n - k)!
P = 16! / (16 - 5)!
P = 16! / 11!
P = 16 x 15 x 14 x 13 x 12 x 11! / 11!
P = 524160
Hence, there are 524160 possible different special pizzas
