P(A) = 0.993 is the probability of event A _ P(A) is the probability of not A (note that I am trying to place a bar over A. I hope you can see it, else it is because the editor did not show it as I intended)
Then, use the fact that the probability of A plus the probability not A is equal to 1: _ => P(A) + P(A) = 1 _ => P(A) = 1 - P(A) = 1 - 0.993 = 0.007
So, the answers are: _ 1) P(A) = 0.07 _ 2) Yes, A is unlikely because its probability is very low.
Hi! a lot of jobs require math in the real world. for instance, a architect has to get all the math correct on a building, otherwise one wrong measurement and it could fall. a lot of jobs involve math.
