Assume that the following events are independent:

• probability that a student is a high school junior is 0.47
• probability that a student is a high school junior and owns a car is 0.14

what is the probability that a student owns a car, given that the student is a high school junior? (round to hundredths)

a)0.07

b)0.30

c)0.33

d)0.61

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

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}
