A box consists of $60$ wall clocks, out of which $40$ are good, $15$ have minor defects and the remaining are broken. A trader will reject the box, if the clock taken out from the box is broken. The trader randomly takes out one clock from the box. What is the probability that :
(i) the box will be rejected ?
(ii) the clock taken out of the box has minor defect ?
(i) the box will be rejected ?
(ii) the clock taken out of the box has minor defect ?

(i) $P(\text{box will be rejected}) = \frac{5}{60}$ or $\frac{1}{12}$ (1 Mark)
(ii) $P(\text{clock has minor defect}) = \frac{15}{60}$ or $\frac{1}{4}$ (1 Mark)
(ii) $P(\text{clock has minor defect}) = \frac{15}{60}$ or $\frac{1}{4}$ (1 Mark)
