the odds against lounging larry winning the horse race are 5:8. determine the probability that lounging larry wins the horse race.
The probability that something happens + the probability that something doesn't happen = 1
if the probability that larry doesn't win the horse race is 5/8, what is the probability he wins?
that doesn't seem right. it would equals 1 - 5/8
1 could also be written as \(\frac{8}{8}\)
no, not that either. do you know how to subtract fractions? can you solve: \[\frac{8}{8} - \frac{5}{8} \]
...wait i may be wrong :/ heh
if the odds that larry loses are 5:8 then that means the probability he loses is 5/13, I believe. which would make 8/13 correct (what you said initially)
because odds means x:y where x is one outcome and y is another. probably is x/y where x is one outcome and y is all possible outcomes.
ok got it thanks alot
