    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: \[\frac{8}{8} - \frac{5}{8} \]

    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.
