In a start-up company which has 20 computers, some of the computers are infected with virus. The probability that a computer is
Alex777 [14]

Answer:

(1) The probability that the technician tests at least 5 computers before the 1st defective computer is 0.078.

(2) The probability at least 5 computers are infected is 0.949.

Step-by-step explanation:

The probability that a computer is defective is, <em>p</em> = 0.40.

(1)

Let <em>X</em> = number of computers to be tested before the 1st defect is found.

Then the random variable X\sim Geo(p).

The probability function of a Geometric distribution for <em>k</em> failures before the 1st success is:

P (X = k)=(1-p)^{k}p;\ k=0, 1, 2, 3,...

Compute the probability that the technician tests at least 5 computers before the 1st defective computer is found as follows:

P (X ≥ 5) = 1 - P (X < 5)

              = 1 - [P (X = 0) + P (X = 1) + P (X = 2) + P (X = 3) + P (X = 4)]

              =1 -[(1-0.40)^{0}0.40+(1-0.40)^{1}0.40+(1-0.40)^{2}0.40\\+(1-0.40)^{3}0.40+(1-0.40)^{4}0.40]\\=1-[0.40+0.24+0.144+0.0864+0.05184]\\=0.07776\\\approx0.078

Thus, the probability that the technician tests at least 5 computers before the 1st defective computer is 0.078.

(2)

Let <em>Y</em> = number of computers infected.

The number of computers in the company is, <em>n</em> = 20.

Then the random variable Y\sim Bin(20,0.40).

The probability function of a binomial distribution is:

P(Y=y)={n\choose y}p^{y}(1-p)^{n-y};\ y=0,1,2,...

Compute the probability at least 5 computers are infected as follows:

P (Y ≥ 5) = 1 - P (Y < 5)

             = 1 - [P (Y = 0) + P (Y = 1) + P (Y = 2) + P (Y = 3) + P (Y = 4)]               =1-[{20\choose 0}(0.40)^{0}(1-0.40)^{20-0}+{20\choose 1}(0.40)^{1}(1-0.40)^{20-1}\\+{20\choose 2}(0.40)^{2}(1-0.40)^{20-2}+{20\choose 3}(0.40)^{3}(1-0.40)^{20-3}\\+{20\choose 4}(0.40)^{4}(1-0.40)^{20-4}]\\=1-[0.00004+0.00049+0.00309+0.01235+0.03499]\\=1-0.05096\\=0.94904

Thus, the probability at least 5 computers are infected is 0.949.
