The following is a two-way frequency table resulting from trials of a model for predicting the yields of different varieties of winter wheat. 112 different tests were carried out. Event A is "the model predicts a yield greater than 10 tonnes per hectare". Event B is "the actual yield is greater than 10 tonnes per hectare". The frequency table is Model Predicts greater than Total 10t/ ha Actual Yield less than 18 24 42 10t/ ha Actual Yield greater than 30 40 7O 10t/ ha What can be said about the events A and B based on the results in this table? Model Predicts less than 10t/ ha IAI Given event A, event B cannot occur AI Events A and B are mutually exclusive IAI Event A is more probable than event B A Given event A, event B must occur A Events A and B are independent
