Evaluate the following: C(7,4) + C(7,5) + C(8,6)

Evaluate the following : "^12C_7 .

Evaluate the following : "^13C_6+ ^13C_5 .

Compute the following: {:[(-1,4,-6),(8,5,16),(2,8,5)]+[(12,7,6),(8,0,5),(3,2,4)]

If " C(n,7)= C(n,5) , find C(n,4) .

Let A = {1, 2, 3, 4,5}, B = {2, 3, 5, 7} and C = {1, 2, 4, 6} be the subsets of the universal set U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. Draw venn diagrams to represent the following : (A nn C)-B .
