Hello, this is an expected value question. Thank you!

The production of coffee in the mountains of Colombia is very sensitive to rainfall during the flowering season, which occurs in the month of February. If rainfall is below 50 mm, flowers don't form and production is only 100 kg per hectare. Rainfall between 50 -- 200 mm is ideal for flowering and production is 1,000 kg per hectare. If rainfall is above 200 mm, flowers form but don't turn into coffee beans so production is only 50 kg per hectare. According to Brazil's National Meteorological Center, the probabilities of different rainfall values are as follows: Rainfall Values (R) Production (P) Probability R less than 50 100 0.25 50
