I had Discrete math in my undergrad CompSci program, I am now in grad school and having to use it again and I am a bit rusty: Need help with verifying some predicate logic translations.

English:Notevery airport has a runway for large jets.

My translation:

hasrunwayfor(x,j,l): true if airport x has a runway for jet j, that is large l, false otherwise

My Formula: ∃x:Airport|∀j:Jet|Runway(j,l)

Do my translation and formula look correct?

Help is greatly appreciated. Thanks in advance
