If P(E) is the probability of the event E, then
Odds for E= (P(E))/(1-P(E))= (P(E))/(P(E'))
(3)/(8)
Odds for E= (P(E))/(1-P(E))
-> (3)/(8)= (P(E))/(1-P(E))
Multiplying both sides by 8 and (1-P(E))
-> 3* (1-P(E))=8* P(E)
-> 3-3P(E)=8P(E)
Adding 3P(E) on both sides
-> 3-3P(E)+3P(E)=8P(E)+3P(E)
-> 3=11P(E)
Dividing both sides by 11
-> P(E)= (3)/(11)
