I'm trying to understand an example given in a book I have. The book is The Theory of Gambling and Statistical Logic, R Epstein, page 16.
"The probability of drawing at least one king in two tries from a deck of 52 cards is 396/(52*51) = 0.149 ."
I know I can solve this question by finding the probability of no king and subtracting from one.
1 - (48/52 * 47/51) = 0.149
In the first example I don't understand where 396 comes from. If I was working from the beginning , how would I get to 396?
