To find the probability that a player will use a Strata golf ball, we need to look at the row for Strata and add up the frequencies: 18+6+4+2=30. Then we divide by the total number of golfers surveyed: 100. So the probability is 30/100 or 0.30. The only answer choice that is close is B, which is 0.20. Therefore, B is the best choice.
