Question

Skye's Ice Cream Shoppe is Mario's favorite place to get ice cream. Unfortunately, because he was late arriving there, his friends had already ordered. He did not know what they ordered for him. They told him that it was either a waffle cone or a sundae and that the ice cream flavor was apricot, chocolate, or blackberry .

a. Make a list of all of the possible ice cream orders.

b. What is the probability that Mario will get something with apricot ice cream?

C. What is the probability that he will get a sundae?

d. What is the probability that he will get either something with chocolate or a waffle cone with blackberry?

e. What is the probability that he will get orange sherbet? ​

Answer 1

a)

• apricot waffle cone
• chocolate waffle cone
• blackberry waffle cone
• apricot sundae
• chocolate sundae
• blackberry sundae

b) 1/3

c) 1/2

d) 1/2

e) 0

Explanation:

a) There are 2 different types of dessert and 3 different ice cream flavors.

Therefore, there are 6 possible ice cream orders:

• apricot waffle cone
• chocolate waffle cone
• blackberry waffle cone

• apricot sundae
• chocolate sundae
• blackberry sundae

b) There are 2 different desserts with apricot ice cream.

⇒ P(apricot ice cream) = 2/6 = 1/3

c) There are 3 combinations of sundae.

⇒ P(sundae) = 3/6 = 1/2

d) P(chocolate) = 2/6 = 1/3

P(blackberry waffle cone) = 1/6

⇒ P(choc) OR P(BWC) = 1/3 + 1/6 = 1/2

e) P(orange sherbet) = 0

as orange sherbet was not an option!
