Answer:
0.623 is the probability that between 800 and 850 files get damaged.
Step-by-step explanation:
We are given the following information:
We treat virus can damage computer as a success.
P( virus can damage computer) = 35% = 0.35
The conditions for normal distribution are satisfied.
By normal approximation:

We have to evaluate probability that between 800 and 850 files get damaged.


0.623 is the probability that between 800 and 850 files get damaged.
