| Abstract: |
| In this paper, we consider a model of blood group test. The existence for the optimum method of grouping is proved when the positive probability of blood sample lies in a deflnite region by using probability theory and difierential calculus. It puts forward a method and derives a formula in questing of the optimum number k of group sample members with the deflnite positive probability. |
| Key words: group test mathematical expectation optimum number k of group sample members iterative formula step function |
