Hospitals typically require backup generators to provide electricity in the event of a power outage. Assume that emergency backup generators fail 31% of the times when they are needed. A hospitalhas two backup generators so that power is available if one of them fails during a power outage. Complete parts (a) and (b) below.a.

Show work for every step. Two types of customers (Preferred and Regular) call a service center. Preferred customers call with rate 3 per hour, and Regular customers call with rate 5 per hour. The interarrival times of the calls for each customer type are exponentially distributed. If the call center opens at 8:00 AM, what is the probability that the first call (regardless of customers type who calls) is received before 8:15 AM?

At a “busy time," a telephone exchange is very near capacity, so callers have difficulty placing their calls. It may be of interest to know the number of attempts necessary in order to make a connection. Suppose that we let p = 0.05 be the probability of connection during a busy time. We are interested in knowing the probability that 5 attempts are necessary for a successful call. Determine the correct parameter. O a.r= 0, x = 5 O b. NONE O C.r= 0, n = 5 d.r = 1, x = 5
Based on a poll, among adults who regret getting tattoos, 28% say that they were too young when they got their tattoos. Assume that nine adults who regret getting tattoos are randomly selected, and find the indicated probability. Complete parts (a) through (d) below. a. Find the probability that none of the selected adults say that they were too young to get tattoos. nothing (Round to four decimal places as needed.) b. Find the probability that exactly one of the selected adults says that he or she was too young to get tattoos. nothing (Round to four decimal places as needed.) c. Find the probability that the number of selected adults saying they were too young is 0 or 1. nothing (Round to four decimal places as needed.) d.

A fair die, with its faces numbered from 1 to 6, is one in which each number is equally likely to land face up when the die is rolled. On a fair die, the probability that the number 6 will land face up is 1/6. A group of students wanted to investigate a claim about manipulating a fair die so that it favors one outcome. The claim states that if a fair die is put into an oven and baked at 200°F for 10 minutes, the inside of the die will begin to melt. When the die cools, the inside will be solid again, but with more weight toward the bottom. This shift in weight will cause the face that was up when the die cooled to land up more often that the other faces. The students obtained a fair die and baked it according to the preceding directions. The die cooled with the number 6 face up. After the die cooled, they rolled the die 200 times, and the number 6 landed face up 43times. Let p represent the population proportion of times the number 6 will land face up on the baked die if the die could…
