Papa John’s Pizza offers the following toppings for cheese pizzas: 3 Meat Toppings: Ham, Pepperoni, Canadian
Problem 1: Papa John’s Pizza offers the following toppings for cheese pizzas:
3 Meat Toppings: Ham, Pepperoni, Canadian Bacon
4 Vegetable Toppings: Mushroom, Green Pepper, Garlic, Tomato.
- John wants to list all the items on the menu. How many ways can he arrange these 7 items on a menu?
- How many possible 3-topping pizzas could you order from Papa John’s
- If you randomly choose a 3-topping pizza, what’s the probability that it will contain all vegetable toppings
- If you randomly choose a 3-topping pizza, what is the probability that it will contain more vegetable than meat topping?
Problem 2: More pizza: You order from two pizza stores A and B. The probability that Store A delivers in 30 minutes or less is 0.95, and the probability that Store B delivers in under 30 minutes is 0.90. Assuming the two pizza companies deliver pizza independently, find the following probability:
- Both pizzas arrive in 30 minutes or less.
- Neither pizza is delivered in less than 30 minutes:
- At least one of the pizzas is delivered on time.
Problem 3: The Candy Company has three machines in operation producing its specialty candies. Machine A produces 8% defective candies, Machine B produces 6% defective candies, and Machine C produces 5% defective candies. Machine A produces 20% of the candies, Machine B produces 30% of the candies and Machine C produces 50% of the candies.
- If you selected a candy at random, what is the probability that it is defective?
- Given a candy is defective, what is the probability that it comes from machine B?
Problem 4: Based on recent records, the manager of a car painting center has determined that following probability distribution for \(X\), the number of customers per day.
| \[x\] | 0 | 1 | 2 | 3 | 4 | 5 |
| \[f(x)\] | 0.05 | 0.2 | 0.3 | 0.25 | 0.15 | 0.05 |
- If the center has the capacity to serve two customers per day, what’s the probability that one or more customers will be turned away any given day?
- By how much must the capacity be increased so the probability of turning a customer away is no more than 0.10?
- Find the cumulative distribution function \(F(x)\).
Problem 5: If the probability density function of \(X\) is
\[f(x)=\left\{ \begin{aligned} & \frac{c}{\sqrt{x}}\text{ for }0<x<4 \\ & \text{ }0\text{ elsewhere} \\\end{aligned} \right.\]
- Determine the value of \(c\).
- Find \(\Pr \left( X<\frac{1}{4} \right)\).
- Find \(\Pr (X>1)\).
Problem 6: If the joint density of \(X\) and \(Y\) is given by
\[f(x,y)=\left\{ \begin{aligned} & \frac{1}{4}\left( 2x+y \right)\text{ for }0<x<1,\text{ }0<y<2 \\ & \text{ }0\text{ for elsewhere} \\\end{aligned} \right.\]
- Find the marginal distribution function of \(X\).
- Find the marginal distribution of \(Y\).
- Find the conditional density function given \(X=\frac{1}{4}\)
