Odds vs Probablity in Math

October 13, 2008
If you flipped three pennies, what would be the odds that they all came out the same?

 Ok... Odds are different from probability
 Probability(x) = (Chances for)/(Total chances)
Odds, on the other hand, are given as: (Chances for) : (Chances against)

So if these are the following solutions:
TTT (000)
TTH (001)
THT (010)
THH (011)
HTT (100)
HTH (101)
HHT (110)
HHH (111)

There are 2/8 solutions that satisfy this. So 1/4 would be the PROBABILITY, but they asked for ODDS which would be 2:6 or 1:3
