Answer:
4000
Step-by-step explanation:
Remark
The expected value is found by multiplying the value by it's probability. For the first one 40% * (- 25000) = - 10000
Breaking even means that you neither add nor subtract a given amount
25% * 0 = 0
35% * 40000 = 14000
So the expected value = - 10000 + 14000 = 4000
