# Relative Frequency and Probability

After observing Michael Jordan’s long-range performance and his probability of making a free-throw shot, we would expect him to perform at approximately a 0.835 percentage. Unfortunately, in 2001–2002, Michael Jordan’s performance fell to a 0.790 percentage. Observing long-run relative frequencies allows us to *predict* the approximate relative frequency.

If we include Michael Jordan’s 2001–2002 performance with the overall data, his career average drops to 0.832. Michael Jordan played one more year. Observing his long-run performance on free throws, we can predict his free-throw percentage to be about 0.832 for his last year.
