Explanation Given information: The number of handshakes needed for 9 justices is 9 × 8 2 . The provided table is Number of Justices Number of Handshakes 2 ( 2 2 ) = 1 3 ( 3 2 ) = 3 4 ( 4 2 ) = 6 5 ( 5 2 ) = 10 6 ( 6 2 ) = 15 7 ( 7 2 ) = 21 8 ( 8 2 ) = 28 9 ( 9 2 ) = 36 Consider the number of handshakes needed for 9 justices is 9 × 8 2 . Since out of n people, every 2 people can have a handshake between them every time
