Hi Tommy,
Wish you a very happy new year :)
2 Types of Crust : Deep Dish, Thin Crust
5 types of toppings
-> Tomatoes
-> Sausage
-> Peppers
-> Onions
-> Pepperoni
2 Types of Pizza's
-> extra cheese
-> regular
In the answer grid, why has the author used combinations to select 4 toppings from a basket of 5 total toppings.
Selecting Tomatoes, Sausage, Peppers, Onions is different from selecting Pepperoni,Tomatoes,Sausage,Peppers (the output in each case is different right ?)
This is what I did
Types of crust can be selected in 2 ways
Types of pizza can be selected in 2 ways
And 4 toppings 2 x 2 x 2 x 2 (Using FCP)
Total : 64 ways
Please let me know.
Thanks :)
