Which of the following pairs of events are mutually exclusive?
Select all correct answers.
Recall in a 52 standard deck of cards, half the cards are red and half the cards are black. Also, face cards can be red or black.
Event A: rolling a 6-sided fair number cube and getting an even number
Event B: rolling a 6-sided fair number cube and getting a number greater than 4
Event A: rolling a 6-sided fair number cube and getting 1
Event B: rolling a 6-sided fair number cube and getting an even number
Event A: drawing a card from a 52-card standard deck and getting a red face card
Event B: drawing a card from a 52-card standard deck and getting a black card
Event A: drawing a card from a 52-card standard deck and getting a face card
Event B: drawing a card from a 52-card standard deck and getting a red card
Answer Explanation
Correct answer:
Event A: rolling a 6-sided fair number cube and getting 1
Event B: rolling a 6-sided fair number cube and getting an even number
Event A: drawing a card from a 52-card standard deck and getting a red face card
Event B: drawing a card from a 52-card standard deck and getting a black card
In the second answer choice, Event A is 1 and Event B is 2,4,6. Since the events have no outcomes in common, they are mutually exclusive.
In the third answer choice, note that a card cannot be both red and black, so it cannot be a red face card and black, so Event A and Event B have no outcomes in common. Therefore, they are mutually exclusive.
Thanks
