Question

In how many ways can a family of six be seated at a round table if the mother and father must sit together?

Answer 1

if it was six people with no conditions, it would be \(5!\) does that help?

Answer 2

I get that, but that does not help

Answer 3

ok you can treat the mother and father as one unit, since they have to sit next to each other
therefore we can think that we have 5 people instead of 6, so it is \(4!\) except...
the mother and father can switch places
so really it is \(2\times 4!\)

Answer 4

Okay that seems reasonable, I will try that answer. Thanks.
