Do not round) Cick to seiect your answers

Explanation / Answer

(a) P(Carton has a puncture) = 0.07

P(Carton has a smashed corner) = 0.08

P(Carton has a smashed corner plus a puncture) = 0.006

so as any carton can have both deformities then these two events are not mutually exclusive so answer (option) B is correct. Events are not mutually exclusive.

(b) Pr(Smashed corner or puncture carton) = Pr(smashed corner) + Pr(puncture carton) - Pr(Smashed corner and puncture carton both)

= 0.07 + 0.08 - 0.006

= 0.144
