There are 6 people models, 2 from Asia, 2 from Europe and 2 from America. How many ways can they arranged such that models from same continent are next to each other?? help please.

In this case, if you imagine the models in 6 chairs, sitting in blocks of 2, such the the models of the same continent are together.

The arrangement would look something like this diagrammatically:

_ _ | _ _ | _ _

B1 B2 B3

The arrangement can be {Asia,Europe,America} {Asia, America, Europe} ...... {America, Europe, Asia} {America, Asia, Europe} making it 6 distinct arrangements where the models can be seated next to each other if they are from the same continent.

Hope I am correct!

Zarrlou Please do verify
