None Mild 64 332 Strong 42 103 Column Total 500 500 Let's use the following notation for the various evenis: W = washing oil off within 5 minutes, A = washing oil off after 5 minutes, N = no reaction, M = mild reaction, 5 = strong reaction. FInd the following probabilities for a person selected at random from this sample of 1000 subjects. (Use 3 decimal places.) (a) PM) x (e) PM! or M). Are the events N = no reaction and M = mild reaction mutually exclusive? Explain. ,0 Type here to search
