The 7-2 odds mean a probabilistic expression of the positive outcome of an event in the betting industry. Such odds mean that out of 9 possible outcomes of an event, there are 7 outcomes of one type and 2 outcomes of the other type. The calculation of the 7-2 odds means that for every 9 events your choice may be successful 2 times, and in other 7 cases your choice will fail. The 7-2 odds are most popular in the UK, particularly in horse racing and football (soccer) matches.
