If the probability of an event happening is 1/7, what are the odds against it happening? What is the ratio of the odds against the event?

the odds that it wont happen are 7/7-1/7=6/7. so your answer is 6/7. I'm not sure what the ratio would be... perhaps 6:7

if probability of an event happening is 1/7

and
if probability of an event not happening is 6/7

ratio of the odds against the event happening vs event happening is
6/7 : 1/7
so, 6 : 1
