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