 	This q pairs work because when the oracle selects b=0:
 
 	There will be no colisions:
-	$$\forall i,k \nexists i,k : i \ne j \land P_{0i} \ne p E_{0i} \implies E_{0i} \ne E_{0j}$$
+	$$\nexists i,k : i \ne j \land P_{0i} \ne p E_{0i} \implies E_{0i} \ne E_{0j}$$
 	there if you don't find any colissions you can assume that the the oracle selected b=0
 
 	if the oracle selects b=1:
