I have five independent events $E_1,E_2,E_3,E_4, E_5$, with their conditional probability values for a given outcome.
Eg - $P(Y|E_1), P(Y|E_2), P(Y|E_3), P(Y|E_4), P(Y|E_5)$
Given the above can I find $P(Y|E_1, E_2), P(Y|E_4, E_3, E_5)$? which is basically any combination of the above events given as the condition. It does not have to be exact even an approximation is sufficient.
