  1. step-by-step explanation:

    i found the life tables for the year 2012. 

    life table of males at age 30. probability of dying between ages x and x+1

    total population:  

    29–30 . . . . . . . . . . . . 0.001030

    30–31 . . . . . . . . . . . . 0.001061

    males:  

    29–30 . . . . . . . . . . . . 0.001420

    30–31 . . . . . . . . . . . . 0.001448

    white population

    29–30 . . . . . . . . . . . . 0.001005

    30–31 . . . . . . . . . . . . 0.001037

    white males

    29–30 . . . . . . . . . . . . 0.001372

    30–31 . . . . . . . . . . . . 0.001399

    non hispanic white population

    29–30 . . . . . . . . . . . . 0.001083

    30–31 . . . . . . . . . . . . 0.001116

    non hispanic white males

    29–30 . . . . . . . . . . . . 0.001477

    30–31 . . . . . . . . . . . . 0.001503

    jacob, non hispanic white male. 30 years old.

    probability that jacob lives to be 30 years old. 

    since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                       

                                              probability of living to be 30 y.o.

    29 - 30 : 1 - 0.001477 = 0.998523

    30 - 31 : 1 - 0.001503 = 0.998497
