College students are randomly selected and arranged in groups of three. The random variable x is the number in the group who say that they take one or more online courses.Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify therequirements that are not satisfied.Does the table show a probability distribution? Select all that apply.ㅁㅁA. Yes, the table shows a probability distribution.B. No, the numerical values of the random variable x are not associated with probabilities.C. No, the sum of all the probabilities is not equal to 1.D. No, not every probability is between 0 and 1 inclusive.E. No, the random variable x is categorical instead of numerical.xP(x)00.10510.35120.39530.149

ANSWER ALL THE PARTS OF THE QUESTION PLEASE A-C (THIS IS NOT A GRADED ASSIGNMENT) a. For a population of patients similar to those described in the stem of this problem, use your chart find the probability that a randomly chosen patient tests positive for strep throat. Write you answer as an abbreviated probability statement with your answer to four decimal places without using a percent symbol. For example, P(strep) = 0.16 b. For a population of patients similar to those described in the stem of this problem, use your chart find the probability that a randomly chosen patient has strep throat AND tests positive. Write you answer as an abbreviated probability statement with your answer to four decimal places without using a percent symbol. For example, P(strep) = 0.16 c.

The percent of fat calories that a person in America consumes each day is normally distributed with a mean of about 36 and a standard deviation of 10. Suppose that one individual is randomly chosen. Let X = percent of fat calories. (a) Find the z-score corresponding to 43 percent of fat calories, rounded to 3 decimal places. (b) Find the probability that the percent of fat calories a person consumes is more than 43. (c) Shade the area corresponding to this probability in the graph below. (Hint: The x-axis is the z- score. Use your z-score from part (a), rounded to one decimal place). Shade: Left of a value Click and drag the arrows to adjust the values. -3 -- 3. -1.5 (d) Find the maximum number for the lower quarter of percent of fat calories. Round your answer to 3 decimal places. (e) Sketch the graph and write the probability statement. 2.
