In how many ways can six people be assigned to three offices if there are two people located in each office

504 ways

Step-by-step explanation:

given data:

no of people = 6

no of offices = 3

no of people in each office = 2

solution:

first we need to find the number of ways 6 people can be shared in 2 or pairs as this is a combination problem.

= 6C2

= 15 ways

ways to place a pair of 2 in 3 offices

= 15 * 3

= 45ways.

using the remaining 4 people we have 4C2 = 6 ways

in the remaining 2 offices

6 * 2 = 12ways

withour conditions

= 45 * 12

= 540ways

considering the constraint

= 4C2

= 6ways

shared in 3 offices

= 6 * 3

= 18 ways

remaining 2 offices

= 18 * 2

= 36 ways

Without constraints - With constraints

= 540 - 36

= 504ways
