The odds against pats winning the election are 6:7 with these odds, what is the probablity that pat will win the election.

Answer 1

odds in favour of some event = prob(event)/prob(not event)

so prob of pat winning = 7/13

check:
prob pat will win = 7/13
prob pat will lose = 6/13

odds in favour of losing = (6/13) / (7/13) = 6/7
or 6 : 7
