need help with this question

As mentioned earlier Klein Barns and Noble Led is truly a very diverse operation! This leaves Fiona with no options. She needs to understand everything from retail operations, processing plants and now farming! Yes, Ann Brightman called bright and early on Wednesday morning whilst Fiona had breakfast. As fall is on its way Ann needed support when deciding to stay with traditional grain or switch over to modified grain. It Is a delicate decision to be made as a good and predictable crop is essential when planning the groups bakery operation., KBN Ltd has a history to stick with traditional grains but Ann like to be innovative and from time to time try new options. The latest report from the Swedish university SLU indicates that a traditional grain would yield a return of 13% in a warm season, 8% in normal conditions and 2% if the season is cold. If a modified grain is chosen the expected return for warm season is 10%, normal 8% and 4% if cold. Ann has captured the latest weather data for the lowlands of Scotland where the big farm KBN owns is situated. Given the change in climate the estimate is that the probability for a warm season is 40%%, "normal" 20% and cold 40%. Ann laughed a little as "normal" has the lowest probability. Now the option is either to go for traditional grains or modified. Fiona looked at Ann and liked to have an option of 20% traditional and 80% modified grains. As Fiona was busy she called you and asked for proper analysis of the situation together with your suggestion for what to do
