(c) Random Experiment: Experiment ațanga result chhuak thei awm zawng zawng zawng hriat lawk theih si; mahse, a result chhuak tur dik tak hriat lawk theih si loh experiment sawina a ni.

(d) Trial: Result pakhat emaw, tam tak emaw pawh chhuah theihna experiment hi a ni Random experiment tih dan sawina a tih theih.

(e)Event: Trial neih atanga result chhuak lak khawm sawina a ni.

(f) Elementary Event: Result pakhat chauh chhuak thei hi a ni.

(g) Equally likely Events: Event atanga result chhuak thei tur zawng zawngte chance neih dan inang vek sawina a ni.

(h) Probability of an Event: Theoretical probability of an event (classical probability tih a ni bawk) chu E tiin dah a ni a, probability of an event chu P(E) tia ziakin, P(E) chu event ațanga result kan hriat duh ber chhuak zat, event neih zawng zawng zata sem a ni, hetiang hian:

P(E)= `Number of outcomes favourable to E`/ Number of all possible outcomes of the Experiment

A chung lam numerator chhuak hi a hnuai lam denominator aia tam a ni thei lo, a tam theih berah a hnuai lam zat a ni thei. Chumi awmzia chu P(E) hi 1 emaw, 0 emaw a nih loh chuan proper fraction a ni ziah tiħna a ni.
