Answer:
Required probability equals 0.18%
Step-by-step explanation:
The probability that the primary and one auxiliary computer fails equals
1) Probability that A and B fails
2)Probability that A and C fails
Thus required probability equals

(-5/6)+(-5/6) have the same denominator (number at bottom of fraction), so all you have to do is add the numerator(top number). So -5 +-5 =-10 . Now you have -10/6, which simplifies to -5/3.
Hope this helps :)
I am not very good you should probably ask someone else sorry

<h3 /><h3>what is indefinite integral?</h3>
When we integrate any function without the limits then it will be an indefinite integral.
