Hi ,
Is there any formula or standard approach kind of thing by which we solve the following problem.?
Q)A photographer will arrange 6 people of 6 different heights for photograph by
placing them in two rows of three so that each person in the first row is standing in
front of someone in the second row. The heights of the people within each row must
increase from left to right, and each person in the second row must be taller than the
person standing in front of him or her. How many such arrangements of the 6
people are possible?
The answer is 5. We can do this by manually forming the arrangements. But I want to know can this be done by the book.
Thank you.
