If P(E) is the probability of the event E, then
Odds for E= (P(E))/(1-P(E))= (P(E))/(P(E'))
(11)/(7)
Odds for E= (P(E))/(1-P(E))
-> (11)/(7)= (P(E))/(1-P(E))
Multiplying both sides by 7 and (1-P(E))
-> 11* (1-P(E))=7* P(E)
-> 11-11P(E)=7P(E)
Adding 11P(E) on both sides
-> 11-11P(E)+11P(E)=7P(E)+11P(E)
-> 11=18P(E)
Dividing both sides by 18
-> P(E)= (11)/(18)
