Let X be the number of applicants who apply for a senior level position at a large multinational corporation. The probability distribution of the random variable X is given in the following table. The outcomes (number of applicants) are mutually exclusive. Complete the table by calculating the cumulative probability distribution of X. Probability distribution Cumulative probability distribution The probability that there will be at least two applicants is The probability that there will be three or four applicants is 0 0.45 Outcome (Number of applicants) 1 3 0.30 2 0.15 0.08 and the probability that there will be at most three applicants is 4 0.02

Fill in the P(X=x) values to give a legitimate probability distribution for the discrete random variable X, whose possible values are -4,-2,3,5, and 6.

Consider a game in which a player rolls one die. If an odd number comes up, the player wins the number of dollars showing on the die. If an even number comes up, the player loses the number of dollars showing on the die. Calculate the expected value for this game. Is the game fair? (Assume that there is no cost to play the game.) The expected value of this game is dollars. (Type an integer or a decimal.)

Fill in the P(X=x)values to give a legitimate probability distribution for the discrete random variable X, whose possible values are −2,1, 3, 4, and 5.

Aircraft turnaround time is defined as the time required to prepare an aircraft for its next flight after arriving at a terminal. Assume that an airline's turnaround time follows a uniform distribution with a minimum time of 22 minutes and a maximum time of 53 minutes. Complete parts a through e. see score a. Determine the probability that the next flight from the airline will require less than 25 minutes to turn around. see scor The probability is (Round to four decimal places as needed.) see sco b. Determine the probability that the next flight from the airline will require between 25 and 45 minutes to turn around. see sco The probability is. (Round to four decimal places as needed.) c. Determine the probability that the next flight from the airline will require more than 45 minutes to turn around. The probability is. (Round to four decimal places as needed.) d. Calculate the mean and standard deviation for this distribution. The mean of the given uniform distribution is u =

A probability distribution function has which characteristic(s)? (Select all characteristic that applies.) Each probability is between zero and one, inclusive. Each probability is larger than one. The sum of the probabilities is one. The sum of the probabilities is larger than one.

A basketball player makes 70% of her free throws. When fouled, she gets to take two free throws. Let X represent the number of free throws made in two tries. The probability distribution for the number of free throws she makes in two attempts is summarized in the following table: Number of free throws made Probability P(X 1) P(X ≤1) 0 O P(X ≥ 1) 0.09 1 The probability statement representing that she makes at least one free throw is expressed as 0.42 2 0.49
