Consider a capital budgeting problem with seven projects represented by binary (0 or 1) variables
\(X_{1},\ X_{2},\ X_{3},\ X_{4},\ X_{5}, X_{6}, X_{7}\)
. Write a constraint modeling the situation in which only 2 of the projects from
\(1,\ 2,\ 3\ and\ 4\)
must be selected. Write a constraint modeling the situation in which at least 2 of the project from
