Answer: $7.80
Explanation:
Based on the information given in the question, the expected profit that the farmer makes will be:
= (Probability of edible stocks × Profit) - (Probability of inedible stocks × Loss)
= (95% × $8) - (5% × $4)
= (0.95 × $8) - (0.05 × $4)
= $7.60 + $0.20
= $7.80
Therefore, the expected profit that the farmer makes is $7.80.
