Comparison can be made according to the following calculation method:
The probability income of the first scheme is: 20000 * 80% =1.6w.
The probability income of the second scheme is: 30000 * 60% =1.8w.
The probability profit of scheme 3 is: 40000 * 40% =1.6w-your topic is incomplete, so we assume that the probability of winning the bid is 40%.
It can be seen that the probability profit of scheme 2 is the largest, so the enterprise should quote 2 10000 according to scheme 2.
