Choose at random a person aged 20 to 39 years. Ask their age and marital status (never married, married, or widowed/divorced/separated). Offered is the probability model for 12 possible answers. Age in years 20 β 24 25 β 29 30 β 34 35 β 39 Never married 0.227 0.156 0.089 0.054 Married 0.027 0.086 0.137 0.148 Widowed/divorced/separated 0.006 0.015 0.022 0.033 (a) Is this a legitimate finite probability model? Select the correct description. Yes. This is a legitimate finite probability model because the probabilities are all greater than 0 and do not sum to 1 . No. This is not a legitimate finite probability model because each probability is between 0 and 1 , and all sum to 1 . Yes. This is a legitimate finite probability model because each probability is between 0 and 1 , and all sum to 1 . No. This is not a legitimate finite probability model because the probabilities are all greater than 0 and do not sum to 1 . (b) What is the probability that the person chosen is a 20 β to 24 β yearβold who is married? (Enter your answer rounded to three decimal places.) P ( 20β to 24βyearβold who is married ) = (c) What is the probability that the person chosen is 20 β 24 years old? (Enter your answer rounded to three decimal places.) P ( 20β24 year old ) = (d) What is the probability that the person chosen is married? (Enter your answer rounded to three decimal places.) P ( married ) =
