(1 point) a new computer virus attacks a folder consisting of 200 files. each file gets damaged with probability 0.2 independently of other files. what is the probability that fewer than 50 files will get damaged?

0.9655

Step-by-step explanation:

Given that a new computer virus attacks a folder consisting of 200 files

Probability for each file gets damaged = p = probability for success in each trial =

Each file is independent of the other.

Hence X no of files damaged is binomial with n =200 and p = 0.20

Here n denotes the number of files and p probability for success in each trial

We have

Required probability

=0.9655

step-by-step explanation:

9 x 8 divided by (5-3)=36
