QUESTION:

Mikes pizza You work at Mikes pizza shop. You have the following information about the 7 pizzas in the oven: 3 of the 7 have thick crust and 2 of the 3 thick crust pizzas have mushrooms. Of the remaining 4 pizzas, 2 have mushrooms. Choose a pizza at random from the oven. (a) Make a two-way table to model this chance process. (b) Are the events getting a thick-crust pizza and getting a pizza with mushrooms independent? Explain. (c) You add an eighth pizza to the oven. This pizza has thick crust with only cheese. Now are the events getting a thick-crust pizza and getting a pizza with mushrooms independent? Explain.

ANSWER:

Step 1 of 5

Given,

No. of pizzas in oven = 7

No. of thick crust pizzas = 3

No. of normal pizzas = 4

No. of normal pizzas with mushrooms = 2

No of pizzas thick crust pizzas with mushrooms = 2
