See the horse D in the previous table.
The odds against horse D were '''18:2''', i.e., '''9:1 (9-1)'''.<br>
A bettor on D bet $1 and got $10 as a result of redistribution of pooled $20, which means the bettor '''earned $9 by betting $1 on horse D'''.
'''Here mathematically calculated odds are completely same as commonly shown odds in a horse race'''.
