# A piggy bank contains hundred 50p coins, fifty Re 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 a Rs 5 coin?

According to the question,

Total number of coins in a piggy bank = 100 + 50 + 20 + 10

= 180

(i) Number of 50 p coins = 100

Probability of a 50p coin = = = (ii) Number of Rs 5 coins = 10

Probability of a Rs 5 coin = = = Hence,

Probability of not getting a Rs 5 coin = 1 -  = Rate this question :
