Question

Need a java program which solves the following problem

(COMPUTER PROJECT) Twenty computers are connected in a network. One computer be- comes infected with a virus. Every day, this virus spreads from any infected computer to any uninfected computer with probability 0.1. Also, every day, a computer technician takes 5 infected computers at random (or all infected computers, if their number is less than 5) and removes the virus from them. Estimate: (a) the expected time it takes to remove the virus from the whole network; (b) the probability that each computer gets infected at least once; (c) the expected number of computers that get infected.

Answer 1

Solutions from the given Information, Here, of spreading visus from one infected Probability to any Other uninfected computer is = 0.1 [P=0.) Computer connected in Network are sn=20 .5 infected computers are randomly taken by technician everyday – 20 days to repair @ Expected time - 2000.1420 - (8 days / ② p (x2) P(xZ1)= 1-P(x<1) P(xcl) = P(x=0) (probability of x-0) using binomial distribution formula. Here, r=0; n=200 p = 0.1/2 = 0.05; q=1-p- 0.95 P(4-0). 20, x 10-0398 (0.95290 >> IX IX 013584 - 0-3585

> plx 21). I-placi) - 1-0.3585 - 10.6415 & Expected no. of Computers get infected {(x) = np (Here, mean of Binomial distribution) 20x0.05 1
Thank you.
