Answer 1

Answer:

The probability that your milkshake consists of at least 1 flavor is 1

Step-by-step explanation:

Parameters:

Number of milkshake bought = 1

Number of flavours sold at the shop = 3

The probability that your milkshake consists of at least 1 flavor:

This means it can have chocolate flavour, or vanilla flavours, or strawberry flavours.

• Probability of having chocolate flavour = 1/3

,

• Probability of having vanilla flavour = 1/3

,

• Probability of having strawberry flavour = 1/3

The probability that your milkshake consists of at least 1 flavor =

1/3 + 1/3 + 1/3 = 3/3 = 1

The milkshake MUST have at least one of these flavours
