Consider a capital budgeting example with 5 projects to select from. Let x_i = 1 if project i is selected, 0 if not, 1 i 5. Write the appropriate constraint. Conditions are independent.

No more than two of the projects can be chosen

		x1 + x2 + x3 2
		x1 + x2 + x3 > 1
		x1 + x2 + x3 + x4 + x5 2
		x1 + x2 + x3 + x4 + x5 > 1
