Determine the probability distribution's missing value. 22. The probability that a tutor will see 0, 1, 2, 3, or 4 students over the course of one hour is: 2 3 4 1 х 4 P(x) 27 27 9 27 a) 9. b) 2 27 c) 25 27 d) 10 27 Find the indicated probability. Empirical evidence suggests that 25% of Florida drivers are uninsured. If four random F are involved in an accident, what is the probability that more than one of them are uninsu 23.

K rch Write out the sample space and assume each outcome is equally likely. Then give the probability of the requested outcomes. A man is shopping for a new patio umbrella. There is a 9-foot and a 12-foot model, and each is available in gray, forest green, and white. (a) He buys a 12-foot forest green umbrella. (b) He buys a 9-foot umbrella. (c) He buys a gray-colored umbrella. Write out the sample space. Choose the correct answer below. OA. {(9-foot, gray), (9-foot, forest green), (9-foot, white), (12-foot, gray), (12-foot, forest green), (12-foot, white)} OB. {(9-foot, 12-foot), (gray, forest green), (forest green, white), (gray, white)} OC. {(9-foot, gray), (9-foot, forest green), (9-foot, white), (12-foot, gray), (12-foot, forest green)} OD. Ø (a) He buys a 12-foot forest green umbrella. The probability is (Type an integer or a simplified fraction.) O t ... er (DELL) Time Remaining: 01:36:59 66°F @ 3 Next 2:27 PM 12/3/2022

K Refer to the sample data for polygraph tests shown below. If one of the test subjects is randomly selected, what is the probability that the subject is not lying? Is the result close to the probability of 0.444 for a negative test result? Consider the result close if the absolute difference is less than 0.050. Did the Subject Actually Lie? No (Did Not Lie) Positive test results Negative test results 10 31 Yes (Lied) 40 9 The probability that a randomly selected polygraph test subject was not lying is (Type an integer or decimal rounded to three decimal places as needed.) because there is Is the result close to the probability, rounded to three decimal places, of 0.444 for a negative test result? Consider the result close if the absolute difference is less than 0.050. a 0.050 absolute difference between the probability of a true response and the probability of a negative test result.

Suppose that a box contains 6 cameras and that 3 of them are defective. A sample of 2 cameras is selected at random, with replacement. Define the random variable � as the number of defective cameras in the sample.Write the probability distribution for �. � P(�=�)

A computer selects a number X from 4 to 11 randomly and uniformly. Round all answers to 4 decimal places where possible. a. What is the distribution of X? X - U(| b. Suppose that the computer randomly picks 39 such numbers. What is the distribution of a for this selection of numbers. a - N( c. What is the probability that the average of 39 numbers will be less than 6.6?

The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children.  a. Find the probability of getting exactly 6 girls in 8 births. b. Find the probability of getting 6 or fewer girls in 8 births.
