Answer:

Day 15

Step-by-step explanation: If you know how to find common denominators or numerators, you do that.

Ksivusya [100]

Answer:

P(X = 0) = 0.42

P(X = 1) = 0.46

P(X = 2) = 0.12

Step-by-step explanation:

We have these following probabilities:

40% probability that the first file is corrupted. So 60% probability that the first file is not corrupted.

30% probability that the second file is corrupted. So 70% probability that the second file is not corrupted.

Probability mass function

Probability of each outcome(0, 1 and 2 files corrupted).

No files corrupted:

60% probability that the first file is not corrupted.

70% probability that the second file is not corrupted.

So

P(X = 0) = 0.6*0.7 = 0.42

One file corrupted:

First one corrupted, second no.

40% probability that the first file is corrupted.

70% probability that the second file is not corrupted.

First one ok, second one corrupted.

60% probability that the first file is not corrupted.

30% probability that the second file is corrupted.

P(X = 1) = 0.4*0.7 + 0.6*0.3 = 0.46

Two files corrupted:

40% probability that the first file is corrupted.

30% probability that the second file is corrupted.

P(X = 2) = 0.4*0.3 = 0.12
