- One coin is tossed twice. Case A is the first shot coming in tails, case B is the second shot coming in tails, and case C is having only one tails. Does the fact that these three events are two by two are independent give the result that all three are independent?Suppose you have two boxes A and B. Box A contains 7 black marbles, 4 white marbles. Box B contains 7 white and 4 black marbles. A random experiment is performed in two sequential trials by first drawing a marble randomly from box A and putting into Box B. In the second trial after the first trial, a marble is drawn randomly from box B. Answer the following questions. Are the two trials independent or dependent? Give reasons to support your answer Draw a probability tree diagram to show the execution of this random experiment. What is the probability of drawing a white marble from box B at the end of 2nd trial? What is the probability of drawing a black marble from box B at the end of 2nd trial? Identify all the mutually exclusive events present in the given scenario and verify that they are mutually exclusive.…if two events A and B are manually exclusive, what is the value of P(A and B)?
- If two cards are drawn without replacement from an ordinary deck, find the probabilities of the following results An ace and a 4 are drawn.We randomly put blue and red marbles into two boxes. It ends up that the first box has 6 blue marbles and 8 red marbles The second box has 6 blue marbles and 2 red marbles. We randomly pick one box, and randomly pick a marble from it. If the marble we picked was red, what is the probability that we drew from the first box?Lori Jeffrey is a successful sales representative for a major publisher of college textbooks. Historically, Lori obtains a book adoption on 36% of her sales calls. Viewing her sales calls for one month as a sample of all possible sales calls, assume that a statistical analysis of the data yields a standard error of the proportion of 0.08. (a) How large was the sample used in this analysis? That is, how many sales calls did Lori make during the month? (c) Using the sampling distribution of p, compute the probability that Lori will obtain book adoptions on 46% or more of her sales calls during a one-month period. (Round your answer to four decimal places.)
- If two cards are drawn without replacement from an ordinary deck, find the probabilities of the following results The second is a face card, given that the first is a jack.We have two boxes, box A (6 blue marbles and 8 red marbles) and box B (6 blue marbles and 2 red marbles). We randomly pick one box, and randomly pick a marble from it. If the marble we picked was red, what is the probability that we drew from the first box?Milo will be having a sports camp next summer. 1 of the Coaches is Coach Mark and he will be handling basketball and volleyball clinics.
