Total families with working mothers = 25 Total families with retired individuals = 10 Families with both working mothers and retired individuals = 8

We want to find out the number of families with working mothers but no retired individuals.

We can use the formula for finding the number of families with working mothers but no retired individuals:

Number of families with working mothers but no retired individuals = Total families with working mothers - Families with both working mothers and retired individuals

Number of families with working mothers but no retired individuals = 25 - 8 = 17

So, there are 17 families with working mothers but no retired individuals as members.
