Answer:

A, B, D

Step-by-step explanation:

For appropriate values of 'a', the log function has the following characteristics:

A: f(1) = 0
B: f(a) = 1
D: f(1/a) = -1

Any log function will tend toward negative infinity as x tends to zero (for |a|>1).

An eyewitness observes a hit-and-run accident in New York City, where 95% of the cabs are yellow and 5% are blue. A police exper

Liula [17]

Answer:

0.1739 = 17.39% probability that the cab actually was blue

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Witness asserts the cab is blue.

Event B: The cab is blue.

Probability of a witness assessing that a cab is blue.

20% of 95%(yellow cab, witness assesses it is blue).

80% of 5%(blue cab, witness assesses it is blue). So

$P(A) = 0.2*0.95 + 0.8*0.05 = 0.23$

Probability of being blue and the witness assessing that it is blue.

80% of 5%. So

$P(A \cap B) = 0.8*0.05 = 0.04$

What is the probability that the cab actually was blue?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.04}{0.23} = 0.1739$

0.1739 = 17.39% probability that the cab actually was blue
