Baryon number distribution and its cumulants have attracted recent interest in the study of a critical endpoint on the QCD phase diagram. We study the baryon number distribution at finite temperature and density using lattice QCD simulations. We employ a canonical formalism to calculate not only cumulants but also the baryon number distribution. We also apply the canonical formalism to a Lee-Yang zero analysis, where Lee-Yang zeros are obtained as roots of a fugacity polynomial. We present results obtained using lattice QCD simulations with two-flavor clover-Wilson fermions for lattice size 8^3x4 and 10^3x4, m_ps/m_V = 0.8.
