Odds are similar to probability, but relate the chance of an event occuring to the chance of the event not occuring rather than to total possible outcomes

The odds against an event is simply the ratio of unfavorable to favorable outcomes for that event.

Since the probability of E is defined to be the number of favorable outcomes
divided by the total number of outcomes possible,

the probability of E is p = a / ( a + b ).

Получается, что шансы - это отношение вероятности возникновения события к вероятности, что оно не возникнет.
Вероятность - это отношение возникновения события к полной сумме событий (вероятность возникновения + невозникновения)

agree  Stanislav Korobov: "Шансы и вероятности содержат одну и ту же информацию, но по-разному выражают ее. Если вероятность того, что событие произойдет, обозначить p, то шансы этого события будут равны p/(1—p)". http://www.mihp.com.ua/mihp_I/Ukraine/Info/Dokazova_med.htm
