✔ 最佳答案
要期望價值定與售價相等，則機構的期望損失 = 0E(x) = 0
(8000)(0.0005) + (6000)(0.001) + (4000)(0.0015) + (2000)(0.002) + (1000)(0.004) + x(0.01) - 30 = 0
0.01x = 6
x = 600

Since the expected value of the ticket equals to the selling price of the tickets.
Therefore,
8000x0.0005+6000x0.001+4000x0.0015+2000x0.002+1000x0.001+(x)x0.01=30
4+6+6+4+4+0.01x=30
24+0.01x=30
0.01x=6
x=600
Therefore,
8000x0.0005+6000x0.001+4000x0.0015+2000x0.002+1000x0.001+(x)x0.01=30
4+6+6+4+4+0.01x=30
24+0.01x=30
0.01x=6
x=600
