Answer:
The coefficient is 
Step-by-step explanation:
The given sum is
We can choose to add only the coeffients of 
or simplify the whole sum.
We collect the LCM for the terms;
This will give us;
Which is the same as
The coefficient is
C: Bc 3 * c = 3c (plus 7 more) = 7+3c
P(most favorable outcome) = 1 -(0.03 +0.16 -0.01) = 0.82
_____
"repair fails" includes the "infection and failure" case, as does "infection". By adding the probability of "repair fails" and "infection", we count the "infection and failure" case twice. So, we have to subtract the probability of "infection and failure" from the sum of "repaire fails" and "infection" in order to count each bad outcome only once.
The probability of a good outcome is the complement of the probability of a bad outcome.
