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.
Step-by-step explanation:
Time Distance
2 3
6 9
10 15
12 18
-13 and -14
They both are consecutive negative integers that multiply to 182.
Thank you sooo much Maddi441
