Sociologists studying social mobility in the U.S. find that the probability that someone who began their career in the bottom 10% of earnings remains in the bottom 10% fifteen years later is 0.59. What is the probability that such a person moves to one of the higher income classes fifteen years later? (Use decimal notation. Give your answer as an exact number.)
probability:

Respuesta :

Using probability of complementary events, it is found that there is a 0.41 probability that such a person moves to one of the higher income classes fifteen years later.

When two events are complementary, the sum of their probabilities are 1.

In this problem, either a person moves to a higher income class or they do not, hence, the events are complementary.

  • 0.59 probability that a person does not move to a higher class.
  • Hence, 1 - 0.59 = 0.41 probability that such a person moves to one of the higher income classes fifteen years later.
