Three sales representatives – J, K and L – rate their (independent) chances of achieving certain levels of sales as follows. Possible sales $10000 $20000 $40000 J Probability 0.3 0.5 0.2 K Probability 0.3 0.4 0.3 L Probability 0.2 0.6 0.2 (For example, J rates her chances of selling $20,000 worth of business as ’50–50’ and K has a 30% chance of selling $30,000) On this evidence, the highest expected sales will be from:
A、J alone
B、K alone
C、L alone
D、K and L
