The answer explains the calculation of arranging six people in a line for a group picture using permutations.
The number of ways six people can be arranged in a line for a group picture can be calculated using the concept of permutations. In permutations, the order of arrangement matters.
To find the number of ways, we can use the formula for permutations of n objects taken r at a time: nPr = n! / (n - r)!
For this case, with 6 people, the calculation would be 6P6 = 6! / (6 - 6)! = 6! / 0! = 6! = 720 ways.
