ANSWER:-
8 couples are attending so total People Attending: 16
Ways To Choose 4 From 16: 16 x 15 x 14 x 13/4! = 1820
Ways To Choose 4 Without Any Couples: 16 x 14 x 12 x 10/4! = 1120
Ways To Choose 4 That Include One Or More Couple: 1820 - 1120 = 700
Probability Of Choosing At Least One Couple: 700/1820 = 35/91 = 5/13.
