In this work, we have studied the single production of Higgs boson in association with a Z boson in dilepton an dijets (llbb) final state using partonic and hadronic level simulations at the Future Circular Collider (FCC-ee) in electron-positron collisions at Ecm=240 GeV and 365 GeV corresponding to an integrated luminosity of 5 /ab. The cross sections have been calculated with and without the initial state radiation (ISR). In the events, Z boson is reconstructed as high-mass dilepton and Higgs boson as two b-jets using b-jet tagging techniques. Dominant backgrounds from two leptons and two jets production are determined from various backgrounds, and fits to dilepton invariant mass distributions of Z boson candidates as well as fits to two jet invariant mass distribution of Higgs boson candidates are used to extract the number of signal events. The ZH production cross section can be measured with a better precision in different ranges of leading lepton momentum at different center of mass energies.
