Answer:
You could order 16 different kinds of pizza.
Step-by-step explanation:
You have those following toppings:
-Pepperoni
-Sausage
-Mushrooms
-Anchovies
The order is not important. For example, if you choose Sausage and Mushrooms toppings, it is the same as Mushrooms and Sausage. So we have a combination problem.
Combination formula:
A formula for the number of possible combinations of r objects from a set of n objects is:
How many different kinds of pizza could you order?
The total T is given by
is the number of pizzas in which there are no toppings. So
is the number of pizzas in which there are one topping is a combination of 1 topping from a set of 4 toppings. So:
is the number of pizzas in which there are two toppings is a combination of 2 toppings from a set of 4 toppings. So:
is the number of pizzas in which there are three toppings is a combination of 3 toppings from a set of 4 toppings. So:
is the number of pizzas in which there are four toppings. So
Replacing it in T
You could order 16 different kinds of pizza.
Answer: 95.55%

Work Shown:
A = event that copier A breaks down
B = event that copier B breaks down
P(A) = probability that copier A breaks down
P(A) = 2% = 0.02
P(B) = probability that copier B breaks down
P(B) = 2.5% = 0.025
P(neither break down) = (1-P(A))*(1-P(B))
P(neither break down) = (1-0.02)*(1-0.025)
P(neither break down) = 0.9555
P(neither break down) = 95.55%
