The contribution of the fourth generation quarks to the rare and decays are studied. Constraints on the extended Cabibbo-Kobayashi-Maskawa matrix elements and are obtained from the existing experimental result for the branching ratio of the decay. The branching ratios of the above-mentioned decays, as well as the photon spectrum in the decay, are studied. It is found that the results are sensitive to the existence of the fourth generation.
