A pizza restaurant is offering a special price with 2 toppings. They offer the toppings: pepperoni, sausage, ham, chicken, green pepper, onion, mushroom and pineapple. Suppose that Rosa’s favorite is sausage and onion, but her mom cannot remember that, and she is going to randomly choose 2 different toppings. If Rosa’s mom will use combination, what are the values of n and r?

• n=8 r=2

• n=8 r=8

• n=2 r=8

• n=6 r=2

From #4, what equation shows the number of ways Rosa can choose 2 toppings?

• P=8!/2!(8-2)!

• P=6!/2!(6-2)!

• P=10!/8!(10-8)!

• P=8!/6!(8-6)!

From #4, how many choices of 2 different toppings can Rosa’s mom choose for the pizza?

• 28

• 16

• 12

• 8

What type of permutation is illustrated in the situation: “The number of arrangements of the letters in the word ISOSCELES is 120.”?

• Indistinguishable Permutation

• Distinct Permutation

• Repeated Permutation

• Circular Permutation

Consider a standard deck of 52 cards. What combination notation will represent the problem if you are asked to determine the different four-card hands that can be formed with at most two queens?

• (48C2 • 4C2) + (48C3 • 4C1) + (48C4 • 4C0)

• 48C0 • 4C4 + 48C3 • 4C1 + 48C0 • 4C4

• 48C2 • 4C1 + 48C3 • 4C0 + 48C0 • 4C3

• 48C4 • 4C0 + 48C1 • 4C4 + 48C4 • 4C4

A card is drawn at random from a standard deck of 52 playing cards. What statement would lead to the probability that a card is an Ace (A) or a King (K)?

• P(A U K) = P(A) + P(K)

• P(A U K) = P(A) - P(K)

• P(A U K) = P(A) ÷ P(K)

• P(A U K) = P(A) × P(K)

What do you call the events that do not have something in common?

• Mutually Exclusive

• Not Mutually Exclusive

• Intersection

• Union
