Answer:

option B

0.30

Step-by-step explanation:

Given in the question,

probability that a student is a high school junior = P(A) = 0.47

probability that a student is high school junior and owns car = P(A∩B) = 0.14

It is question of conditional probability

Formula to use

Probability = P (A∩B) / P (A)

                  = 0.14 / 0.47

                  = 0.297

                  ≈ 0.30

Answer:

0.30

P(A|B) =

P(A and B)

P(B)

=

0.14

0.47

= 0.29787
