In this paper we consider the flat FRW cosmology with a scalar field coupledwith the metric along with generalized Chaplygin gas and perfect fluidcomprising the matter sector. We use the Schutz's formalism to deal with thegeneralized Chaplygin gas sector. The full theory is then quantized canonicallyusing the Wheeler-DeWitt Hamiltonian formalism. We then solve the WD equationwith appropriate boundary conditions. Then by defining a proper completenessrelation for the self-adjointness of the WD equation we arrive at the wavepacket for the universe. It is observed that the peak in the probabilitydensity gets affected due to both fluids in the matter sector, namely, theChaplygin gas and perfect fluid.
