Keith, Annie, Elizabeth, and Marcus are taking a picture. How many different ways can the friends stand in a horizontal line?
Each person can stand 4 different ways I believe So I'm thinking 16 different ways all together.
The number of ways is
4 x 3 = 12
(4 differenct people can be placed in the 1st spot, leaving 3 remaining people to fill the 2nd place)
then there are 2 to fill the third place
24
To find the number of different ways the friends can stand in a horizontal line, we need to count the number of possible permutations.
First, let's determine how many choices we have for the first friend to stand in the line. We have 4 friends, so there are 4 choices for the first position.
After the first friend stands, we have 3 remaining friends to choose from for the second position. So, there are 3 choices for the second position.
Similarly, for the third position, we have 2 remaining friends to choose from.
Finally, for the fourth position, we have only 1 remaining friend.
Therefore, the total number of different ways the friends can stand in a horizontal line is calculated by multiplying the number of choices for each position:
4 * 3 * 2 * 1 = 24
So, there are 24 different ways the friends can stand in a horizontal line.
