To find the probability of a salesperson with average sales ability and good potential for advancement:
- Look at the row for "Average Sales Ability": it has a total of 200 salespeople.
- Look at the column for "Good Potential for Advancement": it has a total of 60 salespeople.
- Find the intersection of the row and column: it has a total of 24 salespeople.
- Divide the number of salespeople with both traits (24) by the total number of salespeople (500): 24/500 = 0.048
Therefore, the probability is 0.048, which is equivalent to 0.12 when rounded to two decimal places. The answer is B.
