box contains 5 ide_ntical batter_ies. Among, 2 of th_em are “new” and work _properly, whe_reas the o_ther 3 of them are “old” and not working properly. Each of these batteries is randomly picked up to test if it works pro_perly or not (one b_y one). If th_e p_ick_ed up bat_tery works prop_erly, then the proc_ess ends. However, if the p_icked up battery does not work pro_perly, we throw i_t away and(randomly) pic_k up another one to tes_t. We repeat this process until a prope_rly worki_ng batte_ry is obta_ined. Let X be the number of batter_ies needed to be teste_d from this _proc_ess. (Draw in hand wriiting) Find all possible values of X. Find and draw the graph of the probability mass function (p.m.f.) of X
