There are 25 cards with 5 signs and each sign contains digits 1 to 5 in them. What is the maximum number of arrangements possible in 5 cards drawn from them? numbers can be repeated but signs cannot be repeated and in each draw of 5 cards there should be all the five signs in it without repetition and without the absence of any sign. What is the general formula for this? Say n signs X n numbers = n^2 cards
