You have a deck of cards what is the probability you draw the sequence of cards without returning each card to the deck after it's drawn: Ace, Jack, 5, and a 7? What is the probability of the 5th card being an odd number? There are two QUESTIONS here...

a) (4/52)x(4/51)x(4/50)x(4/49) There are 4 chances of getting each of them and the deck reduces by one each time. b) For the fifth card you need to know how many of the 48 remaining are odd - there are 40 number cards, half are odd, half even. Three odds have been removed. Therefore there are 17 odd cards. So, the prob is (4/52)x(4/51)x(4/50)x(4/49)x(17/48) I'm now going to read this to see if I'm right! (PS I'm not going to work out the tiny decimal odds...)

The odds of the fifth card being odd is 7 out of 24.
