Elliptic-flow probability distributions ${p}(v_2)$ for charged particles with transverse momentum 0.3 $< p_\\mathrm{T} <$ 3.0 GeV and pseudorapidity $| \\eta | <$ 1.0 are determined for different collision centrality classes. The moments of the ${p}(v_2)$ distributions are used to calculate the $v_{2}$ coefficients based on cumulant orders 2, 4, 6, and 8.
