    3. CThe two events are a result of each other

    3. CThe two events are a result of each other
  3. 3In which type of questions do you have to worry about something being mutually exclusive or not mutually exclusive?
    1. A"And" questions
    2. B"Or" questions
  4. 4What do you do if a problem is not mutually exclusive?
    1. AYou add the two probabilities of the two events together. That's it.
    2. BYou add the two probabilities of the two events together. Then, you subtract the probability of both events occurring at the same time.
    3. CYou multiply the events together.
    4. DYou multiply the events together, then you subtract the probability of the events occurring together at the same time.
  5. 5What do you do if a problem IS mutually exclusive?
    1. AAdd the probability of the two events together. That's it.
    2. BAdd the probability of the events together, then subtract the probability of both events happening at the same time.
    3. CMultiply the probability of the two events together. That's it.
    4. DMultiply the probability of the two events together, then subtract the probability of both events happening at the same time.
  6. 6You have a bag of different colored balls. You have 8 red balls, 6 green balls, and 5 yellow balls. You also have a four-sided die with numbers (1, 2, 3, 4). You want to find the probability of picking a green ball and flipping the die to land on 2. Is this probability mutually exclusive?
    1. AYes, because picking the green ball and the die landing on 2 can happen at the same time.
    2. BYes, because picking the green ball and the die landing on 2 cannot happen at the same time.
    3. CNo, because picking the green ball and the die landing on 2 can happen at the same time.
    4. DNo, because picking the green ball and the die landing on 2 cannot happen at the same time.
  7. 7You have a bag of different colored balls. You have 8 red balls, 6 green balls, and 5 yellow balls. You also have a four-sided die with numbers (1, 2, 3, 4). You want to find the probability of picking a green ball on the first time or picking a red ball on the first try. Is this probability mutually exclusive?
    1. AYes, because the two events can happen at the same time.
    2. BYes, because these two events cannot happen at the same time.
    3. CNo, because these two events can happen at the same time.
    4. DNo, because these two events are happening separately.
  8. 8Label the following events as mutually or not mutually exclusive. In all these questions, you are using a standard deck of cards.
    1.You want to find the probability that you pick a red card or a black card[blank_start].[blank_end]

    2. You want to find the probability of picking a number 9 card or a red card[blank_start].[blank_end]

    3. You want to find the probability of picking a number 4 card or a heart card[blank_start].[blank_end]

    4. You want to find the probability of picking a heart card or a spade card[blank_start].[blank_end]
    1. AMutually Exclusive
    2. BNot Mutually Exclusive
    3. CMutually Exclusive
    4. DNot Mutually Exclusive
    5. EMutually Exclusive
    6. FNot Mutually Excusive
    7. GMutually Exclusive
