    i think that's the Probability of F given that the event E has occurred. Conditional probability

    \[P(A | B) = \text{Conditional probability of A given B}\\P(P\cap B)=\text{Probability of A and B (the intersection of A and B)}\\P(P\cup B)=\text{Probability of A or B (the union of A and B)}\]

    now that you know what \(P(A|B)\) means, see if you can solve below problem |dw:1439733513721:dw|

    sure you can, you don't really need to know that formula you will discover that formula while solving the above problem

    you're given that the person is 70 or older, so "only look at that column" : |dw:1439734227337:dw|
