Question 831303: A bag contains n cards, each having one of the number (1,2,3,...,n) written on it. If all numbers are used, the probability of drawing a card with a number less than or equal to 4 is 1/4. How many cards are in the bag? Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! P()=
Numbers less than or equal to 4 are {1,2,3,4}
P(n<4)=(Cards numbered less than or equal to 4}/{Total number of cards}
