A piggy bank contains hundred 50p coins, fifty Rs 1 coins, twenty Rs 2 coins and ten Rs 5 coins. If it is equally likely that one of the coins will fall out when the bank is turned upside down, what is the probability that the coin (i) will be a 50 p coin ? (ii) will not be Rs 5 coin?
Total no. of coins = 180
No. Of 50 paise coins = 100
No. Of 1-rupee coins = 50
No. Of 2-rupee coin = 20
No. Of 5-rupee coin = 10
(i) Probability of getting 50 paise coin = 100/180 = 5/9
(ii) No. Of not five-rupee coin = 170
Probability of not getting 5-rupee coin
= 170/180 = 17/18
