what are the odds in favor of getting at least one head in three successive flips of a coin?
I need to know the formula on this. I have 1/6 over 1 1/6. But I can't figure out how to do the math. Am I right?

math 
bobpursley,
the probability of getting at least one head is = 1prob(three tails)=11/8=7/8
so the odds are 7:1 to get at least one head.

Monique/G,
It' is the other way around if you multiplt your runner.
