Concept explainers
To find : Probability that the operation is successful for someone who has an operation that is free from infection
Answer to Problem AP2.9CPT
b. 0.84
Explanation of Solution
Given information : Infection occurs in 3% of operations, the repair falls in 14%, and both infection and failure occur together 1% of the time
Let A denotes the
P(A)=3/100,P(B)=14/100,P(Aâ‹‚B)=1/100
So,
P(A'⋂B' )=P(A∪B)'=1-P(A∪B)
=1-[P(A)+P(B)-P(A∩B) ]
=1-(3/100+14/100-1/100)
=1-16/100
=84/100
=0.84
Option b. is correct
