Answer:
The expected completion time of the project is 305 days
Explanation:
Given
Expected days = 150, if the weather is dry and hot.
Expected days = 350, If the weather is damp and cool
Otherwise, it is expected to take 300 days.
Chance of cool damp weather = 40%
Chance of hot dry weather = 10%
Chance of other weather = 100% - 40% - 10% = 50%
The expected completion time of the project is calculated as follows;
(Expected days when cool and damp) + (Expected days when hot and dry) + (Others)
= 350 * 40% + 150 * 10% + 300 * 50%
= 305 days
The expected completion time of the project is 305 days
