help with math.random

[xxnukzxx]

Hey, so i have this code so far:
houses = { "Hufflepuff", "Gryffindor", "Slytherin", "Ravenclaw" }
classrooms = { "Class 1", "Class 2", "Class 3", "Class 4" }
classes = { "Charms", "Wizardry", "Muggle Studies", "DADA", "Transfiguration", "History of Magic", "Herbology", "Astronomy", "Potions", "Quidditch", "Free Time", "Great Hall", "Lock Down" }

concommand.Add( "newclass", function( ply, cmd, args )
print( "I pick" .. houses[math.random( 1, #houses )] .. "to go to" .. classes[math.random( 1, #classes )] .. "in class room".. classrooms[math.random( 1, #classrooms )] )
end )

I was wondering if anyone could help me write a code that would get the output of a class and assign a certain classroom.

Example: if table.random for classes is "Potions", then (i'll do my code)

Make it a variable and do an if statement?
