You are told that PA I B) = PBIA). Which statement below must be true?

ivann1987 [24]

Answer:

A and B are equally likely

Explanation:

The conditional probability is defined as follows:

$P(X|Y)=\frac{P(X\cap Y)}{P(Y)}$

where:

$P(X|Y)$ is the probability for X to occur, given that Y has occurred

$P(X\cap Y)$ is the probability that both X and Y occur at the same time

$P(Y)$ is the probability for Y to occur

Given two events A and B, we have:

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

and

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

In this problem, we are told that

$P(A|B)=P(B|A)$

Which means that:

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

Simplifying, we get:

$P(A)=P(B)$

which means that A and B are equally likely.

The closest known star to our solar system is Alpha Centauri, which is approximately 4.30 light-years away. A spaceship with a c

Nadusha1986 [10]

Answer:

2.58 years.

Explanation:

As the earth would be in 4.3 years approaching the space ship, thus to to find out the time the equation of

Δtr ⇒ Δto √1-v2 / c2

i.e the relative time, observed tome and the velocity and light speed, will equal to time of 2.58 years as the velocity is 0.8 c.

Warm, humid, growing, part of United States with important oil discoveries - South.

Northern part of this peninsula is heavily populated, near San Diego - Baja California.

Vast forests and active volcanoes in the United States - Pacific Northwest.

Includes area around the American and Canadian shores of the Great Lakes - Midwest.

<h3>What is a sub-region?</h3>

This refers to the conceptual unit which derives from a larger region or continent and is usually based on location.

For instance, in the United States, the subregion of the country includes the Pacific Northwest, Midwest, Baja California, South etc.

Therefore, in this question, the sub-region were used to locate the region where we have:

Warm, humid, growing, part of United States with important oil discoveries
Northern part of this peninsula is heavily populated, near San Diego
Vast forests and active volcanoes, in the United States
Includes area around the, American and Canadian shores of the Great Lakes.
