4.(2 pts) A computer lab consultant has to check the functionality of the printers in a certain building. Suppose that 7% of printers have defects, and defects occur independently of each other. Find the probability of exactly 2 defective printers in the building that has thirty printers.
Homework Answers
Here, n = 30, p = 0.07, (1 - p) = 0.93 and x = 2
As per binomial distribution formula P(X = x) = nCx * p^x * (1 -
p)^(n - x)
We need to calculate P(X = 2)
P(X = 2) = 30C2 * 0.07^2 * 0.93^28
P(X = 2) = 0.2794

QUESTION 14 The on-line access computer service industry has grown at an extraordinary rate. Current estimates suggest that only 30% of the home-based computers do not have access to on-line services. This number is expected to decrease substantially over the next five years. Suppose 20 people with home-based computers were randomly and independently sampled. What is the probability that exactly 7 of those sampled do not currently have access to on-line services? 1..0428 2..3921 3..6079 4..1643 QUESTION 15 The on-line...

Problem 2. Suppose a website sells X computers where X is modeled as a geometric random variable with parameter pi. Suppose that each computer is defective (i.e., needs to be returned for repair or replacement). independently with probability p2. Let Y be the mumber of computers sold which are defective. For this problem, recall that a geometric random variable X with parameter pi has pmf otherwise (a) Find ElY. (b) Find Var(Y). (c) Find P(Y 0).
