The tunneling spectroscopy and shot noise in ferromagnet/insulator/triplet-superconductor (FM/I/tripletSC) structures are studied by taking into account the roughness interfacial barrier and exchange splitting in the FM.For the triplet-SC of Sr2RuO4, we consider two-dimensional f-wave order parameter symmetries having nodes within the RuO2 plane, which reasonably describe both thermodynamic and thermal conductivity data. It is shown that the ferromagnetic exchange splitting gives rise to a decrease in the differential conductance, the average current, and the shot noise power, while the noise power-to-current ratio is increased; the interface roughness is found to lead to a decrease in the differential conductance and the average current, and an increase in the noise power-to-current ratio.
