[Calculating Probability from Data] The table below gives details of symptoms that patients presented and whether they were suffering from meningitis. Using this dataset, calculate the following probabilities (4 points): a) P ( Fever = true ) b) P (Headache = false 0 R Meningitis = true ) c) P ( Headache = true AND Vomiting = false ) d) P ( Meningitis = false ( Fever = false, Vomiting = true )) .
