Suppose that you have torn a tendon and are facing surgery to repair it. the orthopedic surgeon explains the risks to you. infection occurs in 3% of such operations, the repair fails in 14%, and both infection and failure occur together 1% of the time. what is the probability that the operation is successful for someone who has an operation that is free from infection?

A: outcome has no infection and repair that does not fail

B: outcome has no infection

P(A | B) = P(A and B) / P(B)

For P(A and B) that's the same as P(A).  We fail in .03+.14-.01 of the cases, so

P(A) = 1 - (.03+.14-.01) = 1-.16 = 0.84

P(B) =  1 - .03 = .97

P(A|B) = .84/.97 = .866

86.6%

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
