You have torn a tendon and are facing surgery to repair it. the surgeon explains the risks to you: the probability of infection
skad [1K]
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.

What is the point slope form of a line with slope 2 that contains the point (1, -1)
mezya [45]
Point slope form is y - y1 = m(x-x1)

So,

y - (-1) = 2(x - 1)
y + 1 = 2x -2 or y + 1 = 2(x -1)

Hope this helps :)
