# Probability of Flush losing (percentage)

MichaelBartmess.Probability of Flush losing (percentage)

This Probability of Flush losing (percentage) equation defines the probability that another hand can beat your flush and this probability is expressed as a percentage. The **Flush** can be beaten by all the hands of greater value: full house, four of a kind, straight flush, and royal flush. So the probability that an opponent has a hand that can beat your hand is the sum of all the higher value hands' probabilities, plus the probability that your opponent has a **Flush** with a higher high card value. See Notes Page for further explanation.

## NOTES

The probability that you can be beat is the sum of the probabilities of any hand that can beat your **Straight**. Each of those probabilities is based on the ratio of the combinations of ways to be dealt those winning hands to the number of five card hands possible,`((52),(5))`. The total number of five card hands possible is computed as `((52),(5))` (see the constant defining number of five card hands).

The probabilities that must be summed are:

- The probability of being dealt a flush
- The probability of being dealt a full house
- The probability of being dealt four of a kind
- The probability of being dealt a straight flush
- The probability of being dealt a royal flush
- The probability of being dealt a straight with a higher top card value

** note that if two straights have the same value, for example, 4,5,6,7,8 and 4,5,6,7,8, they split the pot.
