A baseball player’s slugging percentage is the average number of hits a batter gets in all the “at bats” they have in their games played. This statistic differs from their batting average in that it is weighted based on the number of bases run for a single hit. Babe Ruth had 8399 “at bats” in his career where he had 714 home runs (4-base hits), 136 triples (3-base hits), 506 doubles (2-base hits), and 2873 singles (1-base hits). What was his slugging percentage?
