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
