A class with n kids lines up for break. The request in which the children line up is arbitrary with each requesting being similarly likely. There are three children in the class named John, Betty, and Mary. The utilization of "or" in the depiction of the occasions, ought to be deciphered as the comprehensive or. That is "An or B" implies that An is valid, B is valid, or both An and B are true.Give an articulation for every one of the probabilities underneath as an element of n. Improve on your last articulation however much as could reasonably be expected so your answer does exclude any declarations of the structure (an over b).

(a) What is the likelihood that Betty is preferred choice or Mary is toward the end in line?

(b) Explain the technique used to compute likelihood.

3. Decide whether the connection between's the two given factors is probably going to be positive or negative, or in the event that they are not prone to show a direct relationship.

a) An individual's age and the lucidity of their vision.

b) The occasions an individual activities each week and the measure of time they

spend on the telephone.

c) The quantity of rooms in a home and its selling cost.

d) Number of Coronavirus positive cases Vs Age of an individual.

The accompanying yield was acquired from a various relapse investigation.
