here is what I did

|dw:1348935331451:dw|

so what is your answer

well, I thought it was 2/15 but I am having second thoughts

you want P(senior|flu) correct?

yes, probability of people with flu who are senior

\[P(S|F)=\frac{P(F|S)P(S)}{P(F)}\]

so , P(F|S) is what I found to be 2/15?

\[P(F|S)=\frac{2}{5}\]

ok,
also
is this a defination
\[P(S|F)=\frac{P(F|S)P(S)}{P(F)}\]

\[P(A|B)=\frac{P(A\cap B)}{P(B)}\]
is the definition of conditional probability

use this definition twice to get the formula I have above

wow, thank you very much

np

do you have a new final answer?

(2/5)(1/3)
--------- =
(1/5)
2/15
----- =
1/5
2/15 * 5/1=2/3
