Plant oils cause the reaction. Researchers at Allergy Institute did a study to determine the effects of washing the oil off within 5 Reaction Within 5 Minutes After 5 Minutes Row Total minutes of exposure. A random sample None 420 43 463 of 1000 people with known allergies to Mild 61 325 386 poison ivy participated in the study. Oil Strong 19 132 151 from the poison ivy plant was rubbed on a patch of skin. For 500 of the subjects, Column Total 500 500 1000 it was washed off within 5 minutes. For the other 500 subjects, the oil was washed off after 5 minutes. The results are summarized in the following table. Let's use the following notation for the various events: W= washing oil off within 5 minutes, A = washing oil off after 5 minutes, N= no reaction, M = mild reaction, S = strong reaction. Find the following probabilities for a person selected at random from this sample of 1000 subjects. (Use 3 decimal places.)
