Statistics Question
Flip up 5 cards out of a standard 52 card deck. The probability that at least 1 will be a spade?
Please show me HOW to do the math. I can do other things statistics-wise, but I'm whiffing big time on this one. |

1 - (39/52)*(38/51)*(37*50)*(36/49)*(35/48)

Re: Statistics Question
This is a grunch
The odds of there being at LEAST 1 spade is easiest to calculate as follows 1.00 - the odds of there being NO spade. The odds of there not being any spade is 39/52 * 38/51 * 37/50 * 36/49 * 35/48 which is ~ 22.15% Thus the odds of there being at least one spade on the board is ~ 77.85% (this goes for any suit of course) (that is to say, the total number of boards without spades divided by the total number of boards period). |
