Describing Events as Subsets of a Sample Space Using Characteristics of Outcomes

The event “A and B” is called the ____________ of events A and B. It consists of all outcomes that are common to both events, and is denoted A∩B.

Let A be the event that a die lands on a number greater than 3. Let B be the event that the die lands on a multiple of 2. Which are the possible outcomes of A ∩ B? Select the two that apply.

• 2

• 3

• 4

• 5

• 6

The occurrence of two events at the same time.

• Intersection

• Union

• Mutually Exclusive

• Conditional

The probability of an event NOT happening.

• probability

• complement

• experimental probability

• sample space

Define the complement of:

Event A= The number selected is greater than 14

• The number selected is equal to 14

• The number selected is less than 14

• The number selected is less than or equal to 14

• The number selected is greater than 15

Suppose a 2 is rolled on a number cube with sides numbered 1, 2, 3, 4, 5, and 6. Which outcome(s) make up the complement of this event? Select all that apply.

• rolling a 3

• rolling a 5

• rolling a 6

• rolling a 4

• rolling a 1

Experimental Probability

The complement of an event is found by ?

• P(event)

• 1 + P(event)

• P(event) / Odds

• Odds / P(event)

A bag contains 5 red cards, 4 yellow cards, and 7 blue cards. A card is randomly drawn from the bag. If Y is the event of drawing a blue card, what does the complement of Y mean?

• The complement of Y is drawing a red card.

• The complement of Y is drawing a non-blue card.

• The complement of Y is drawing a yellow card.

• The complement of Y is drawing no card.
