Alternatives can consist of various Alternatives can consist of various investment proposalsinvestment proposals

Proposals can be:Proposals can be: Mutually exclusiveMutually exclusive IndependentIndependent Contingent upon another proposalContingent upon another proposal

Mutual ExclusiveMutual Exclusive

At most one project out of the group At most one project out of the group can be chosen:can be chosen:

If I have proposals A, B, and C------- If I have proposals A, B, and C------- only A or B or C can be chosen (not a only A or B or C can be chosen (not a combination)combination)

IndependentIndependent

All, none or any combination may be All, none or any combination may be selectedselected

Total number of alternatives = 2Total number of alternatives = 2mm where m is the number of proposalswhere m is the number of proposals

If there are 4 proposals, the total If there are 4 proposals, the total number of options is 2number of options is 244 = 16 = 16 alternativesalternatives

ContingentContingent

The choice of a project is conditional The choice of a project is conditional on the choice of another projecton the choice of another project

If A is contingent on B then A can’t be If A is contingent on B then A can’t be implemented unless B is also implemented unless B is also implementedimplemented
