When a single card is drawn from an ordinary 52-card deck, find the odds in favor of getting the 4 of spades.
This is the answer I got, could someone tell me if I have done it correctly?
Odds in favor of A = Number of ways A could occur / 1 - Number of ways A could not occur
Odds in favor of getting a 4 of spades = 1/52 / 1 - 1/52
= 1 :: 51
The odds are 1/52 of getting the four of spades and 51/52 of not getting it.
