Piggy bank contains 100 fifty-paise coins, 50 one-rupee coins, 20 two-rupees coins and 10 five- rupees coins. One coin is drawn at random. Find the probability that the drawn coin

(i) will be a fifty-paise coin (ii) will not be a five-rupees coin.

Total no of coins = 100+50+20+10 = 180


No of 50 paise coins = 100


No of one rupee coins = 50


No of two rupees coins = 20


No of five rupees coins = 10


(i) Probable outcome that the coin is 50 paise coin = 100


⇒ probability



(ii) Probable outcomes that it is a five rupee coin = 10


⇒ probability
