"Probability"
"Odds"
"The odds of rolling a 4 with a fair 6-sided die is P(4) / (1-P(4)) = 1/6 / (1-1/6) = 0.2. Think of odds as the ratio between how often the event of interest occurs (rolling a 4 in this example) divided by how often all the other outcomes occur, i.e. excluding the event of interest."
