32 different combinations of three cars can the Carsons select if all the cars are to be different colors.

B. 32

<u>Explanation:</u>

As it is given there are four available colours of the car. That means we have 4 cars. 2 \times 4 =8. Now choose the first car. The no.of way of choosing the first car is equalled to 8 and imagine the first car Colour is black. Now we have a black car so we have to choose from 6 options apart from black.

Now no.of way of choosing the 2 car = 6 and imagine it is blue. Now we have to choose two colour car, so now we have 4 options to choose from. The no.of choosing the car = 4. Now let's calculate the total arrangement - 8 \times 6 \times 4=192. It is the total calculation for three cars.

But we have to know the selection so three cars can also be arranged in 6 ways. So the number of different combinations of three cars can be calculated as 192÷6= 32. This is how the selection is being done.

VARVARA [1.3K]

Answer:

During the American Civil War, President Abraham Lincoln gave a speech at Gettysburg's National Cemetery on November 1863, to honor the Soldier's commitment, it was called <em>"The Gettysburg Address"</em>, which conveyed his thought about life, politics, and morality, and pointing out how men are created equal, to emphasize this to the beginning of the new nation recently founded, alluding to the declaration of independence and appealing to the people's sentiment and feelings of uncertainty and skepticism about the Civil War's worthiness, in order to infuse confidence, by making the parallel associating that stage in importance with the early foundation of the country.

He positioned the events as a step forward in the right direction to mark the American history as it was intended with the <em>Declaration of Independence</em>, repeatedly using the statement <em>"The Union"</em> all the way, as synonym of a new nation, setting out a broader definition of Liberty.
