Consider all 3 element subsets of the set {1, 2, 3, ………. 300} then:

Answer»

NUMBER of these subsets for which Sum of the three elements is multiple of 3 is`3xx""^(100)C_(3)+100^(3)`
Number of these subsets for which sum of the three elements is not a multiple of 3 is `3xx""^(10)C_(3)+100^(3)`
Number of these subsets for which sum of the three elements is even is `""^(151)C_(3)+149xx""^(150)C_(2)`
of these subsets for which sum of the three elements is even is`""^(300)C_(2)-""^(150)C_(3)`
