1. [-/1 Points] DETAILS TANFIN12 7.3.004. MY NOTES A pair of dice is rolled, and the number that appears uppermost on each die is observed. Refer to this experiment, and find the probability of the given event. (Enter your answer as a fraction.) A double is thrown. Need Help? Read It 2. [-/1 Points] DETAILS TANFIN12 7.3.008. MY NOTES PRACTICE ANOTHER An experiment consists of selecting a card at random from a 52-card deck. Refer to this experiment and find the probability of the event. (Enter your answer as a fraction.) A club or a queen is drawn. Need Help? Read It 3. [-/1 Points] DETAILS TANFIN12 7.3.010. MY NOTES PRACTICE ANOTHER An experiment consists of selecting a card at random from a 52-card deck. Refer to this experiment and find the probability of the event. (Enter your answer as a fraction.) A black face card is drawn. Need Help? Read It 4. [-/1 Points] DETAILS TANFIN12 7.3.018. MY NOTES PRACTICE ANOTHER Is the statement correct? The probability that a certain stock will increase in value over a period of 1 week is 0.8. Therefore, the probability that the stock will decrease in value is 0.2. Correct, because the sum of the probabilities equals 1. Incorrect, because the sum of the probabilities does not equal 1. Incorrect, because the value of the stock could stay the same. Incorrect, because the time period needs to be shorter than a week. Incorrect, because the time period needs to be longer than a week Need Help? Read It 5. [-/1 Points] DETAILS TANFIN12 7.3.020. MY NOTES PRACTICE ANOTHER Is the statement correct? Joanne, a high school senior, has applied for admission to four colleges, A, B, C, and D. She has estimated that the probability that she will be accepted for admission by college A, B, C, and D is 0.6, 0.2, 0.1, and 0.06, respectively. Thus, the probability that she will be accepted for admission by at least one college is P(A) + P(B) + P(C) + P(D) = 0.6+ 0.2 + 0.1 + 0.06 = 0.96. Correct, because P(A) + P(B) + P(C) + P(D) = 0.96. O Incorrect, because P(A) + P(B) + P(C) + P(D) # 1. Incorrect, because the probabilities should be multiplied instead of added. Incorrect, because she forgot to divide by four to find the average. Incorrect, because these events are not mutually exclusive. Need Help? Read It Watch It 6. [-/4 Points] DETAILS TANFIN12 7.3.024. MY NOTES PRACTICE ANOTHER Let E and F be two events of an experiment with sample space S. Suppose P(E) = 0.5, P(F) = 0.3, and P(En F) = 0.1.
