Answer:

Option E

P(B|A) is not equal to P(B).

Explanation:

Two events are said to be dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probability is changed. Also, Two events are said to be independent if occurrence of the first does not affects the outcome  of the second so that the probability is not changed.

For independent events: P(A and B) = P(A) x P(B).

Recall that P(B|A) = P(A and B) / P(A)

= P(A) x P(B) / P(A) = P(B).

Therefore, for dependent events, P(B|A) is not equal to P(B).

The preamble of the U.S. Constitution was written in part to explain why the new form of government differed from the English sy
uranmaximum [27]
The Preamble of the United States writes as this:

"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."

The purpose of the Preamble was to introduce the set of laws that would pave the way for America. Coming from a Monarchy, the Founding Fathers did not want their newly formed country to follow the same rules as Great Britain.

Hence, the Constitution was written to explain the idea that the people of the United States would have a say in the laws of the country, and well as explain the democracy America would soon become.

Based on this information, I would answer "True" to your question.

If all objects have some gravitational force then why don’t objects on earth move towards each other?
Mekhanik [1.2K]

<u>Answer:</u>

<em>The appropriate response is gravity: an undetectable power that pulls objects toward one another.</em>

<u>Explanation:</u>

Thus, the closer items are to one another, the more grounded their gravitational draw is. Earth's gravity originates from all its mass. <em>All its mass makes a consolidated gravitational draw on all the mass in your body.</em>

The power/mass proportion is the equivalent for each. A straightforward guideline to hold up under as a primary concern is that all items <em>(paying little heed to their mass)</em> experience a similar increasing speed when in a condition of free fall.

<em>At the point when the main power is gravity, the speeding up is a similar incentive for all articles. On Earth, this speeding up worth is 9.8 m/s.</em>
