Question

student ID: 62200095

Parametric Questions e.g. Student ID=61190003 averageD(6+1+1+9+0+0+0+3)/8) x 0.01 = 20/8 = 2.5 then round the number to an lower integer t [2.5] = 2; a = (2 mod 4) +3 = 2+3 = 5 a =t mod 4 +3 4. A slitter assembly contains 30 blades. Four blades are selected at random and evaluated each day for sharpness. If any dull blade is found, the assembly is replaced with a newly sharpened set of blades. a. If A of the blades in an assembly are dull, what is the probability that the assembly is replaced the first day it is evaluated? b. If A of the blades in an assembly are dull, what is the probability that the assembly is not replaced until the third day of evaluation? [Hint: Assume that the daily decisions are independent, and use the geometric distribution.] c. Suppose that on the first day of evaluation, 2 of the blades are dull; on the second day of evaluation, 6 are dull; and on the third day of evaluation, 10 are dull. What is the probability that the assembly is not replaced until the third day of evaluation? [Hint:Assume that the daily decisions are independent. However, the probability of replacement changes every day.]
