A card is drawn from a deck of cards 1 to 20 the card is not replaced and another is drawn what is the probability that a prime number is drawn and then composite number?

There are 8 prime numbers (2, 3, 5, 7, 11, 13, 17, 19) between 1 and 20, the rest are comp. P(prime then comp) = (8/20) * (11/20) = .22 There is a 22% chance you will draw a Prime number followed by a composite number. ...maybe...
