(A) Total number of coins in the piggy bank $= 100 + 50 + 20 + 10 = 180$.$(i)$ Number of $50\, p$ coins $= 100$.Probability of getting a $50\, p$ coin $= \frac{	ext{Number of favourable outcomes}}{	ext{Total number of outcomes}} = \frac{100}{180} = \frac{5}{9}$.$(ii)$ Number of $Rs.\, 5$ coins $= 10$.Probability of getting a $Rs.\, 5$ coin $= \frac{10}{180} = \frac{1}{18}$.Probability of not getting a $Rs.\, 5$ coin $= 1 - P(	ext{getting a } Rs.\, 5 	ext{ coin}) = 1 - \frac{1}{18} = \frac{17}{18}$.
