Probability

What is the Probability of NOT picking a specific item?

• Probability of NOT picking an item = 1 - Probability of picking that item.

• Probability of NOT picking an item = Probability of picking that item.

• Probability of NOT picking an item = 0.5.

• Probability of NOT picking an item = Probability of picking that item squared.

What is a Compound Event?

• An event that occurs only once.

• An event that involves two or more simple events.

• An event that cannot be predicted.

• An event that is always certain.

How many different combinations can be made with 3 shirts and 4 pants?

• 8 combinations (2 shirts × 4 pants = 8)

• 10 combinations (5 shirts × 2 pants = 10)

• 12 combinations (3 shirts × 4 pants = 12)

• 15 combinations (3 shirts × 5 pants = 15)

What is a Sample Space?

• A sample space is the set of all possible outcomes of a probability experiment.

• A sample space is a collection of all the events that can occur in a probability experiment.

• A sample space is the average of all outcomes in a probability experiment.

• A sample space is the maximum outcome that can occur in a probability experiment.

What is the Probability of selecting a red card from a standard deck of cards?

What is the Fundamental Counting Principle?

• The Fundamental Counting Principle states that if one event can occur in 'm' ways and a second event can occur independently in 'n' ways, then the two events can occur in m × n ways.

• The Fundamental Counting Principle states that the total number of outcomes of an event is the sum of the outcomes of each individual event.

• The Fundamental Counting Principle states that if two events are dependent, the total number of outcomes is the product of the outcomes of each event.

• The Fundamental Counting Principle states that the probability of an event is equal to the number of favorable outcomes divided by the total number of outcomes.

How do you find the total number of outcomes for multiple choices?

• Add the number of choices for each category (e.g., colors + sizes + styles).

• Multiply the number of choices for each category (e.g., colors × sizes × styles).

• Choose the maximum number of choices from any category.

• Count the number of categories and multiply by two.

What is the Probability of rolling a 3 on a standard die?

• 1/6 (There is 1 favorable outcome and 6 possible outcomes)

• 1/3 (There are 2 favorable outcomes)

• 1/4 (There are 3 favorable outcomes)

• 1/2 (There are 3 favorable outcomes)
