Suppose that six of these individuals are randomly assigned to a particular examiner, and let X be the number among the six who are taking the test for the first time.

(a)What kind of a distribution does X have (name and values of all parameters)?

(b)Compute

P(X = 4), P(X ≤ 4), and P(X ≥ 4).

(Round your answers to four decimal places.)

P(X = 4)=

P(X ≤ 4)=

P(X ≥ 4)=

(c) Calculate the mean value and standard deviation of X. (Round your answers to three decimal places.)
