Tarot cards are used for telling fortunes, and in a reading, the arrangement of the cards is as important as the cards themselves. How many different readings are possible if four cards are selected from a set of seven Tarot cards?

1. not combinations because order does not matter in combinations
we need permutations of 7 taken 4 at a time
p(n,r) = n!/(n-r)!
= 7!/3!
= 7*6*5*4 = 840
