Total no. of ways in which 5 men & 3 women can sit around circular table=7!.

Arranging 5 men around a table = 4!

This creates 5 vacant positions to be filled by women

choose in 3 of them and shuffle = 5c3 x 3!

Total no. of ways in which no two women are adjacent=4!*5c3 x 3!=5!*3!

P(no two women are adjacent)=(5!*3!)/7!=1/7..i.e option a)1/7...
