The computer virus attacks a folder consisting of 28 files. The virus corrupts
the files independently of each other. Each file is corrupted with a probability of 0.034.
What is the probability that the virus will corrupt 4 files?
~~~~~~~~~~~~~~~~~~
It is a binomial type experiment.
The number of trials is n= 28.
The number of success trials is k= 4.
The probability of success in each individual trial is p= 0.034.
Use the standard binomial formula for the probability
P = = =
= = 0.01193 (rounded). ANSWER
