(I) will be a 50 p coin?

(ii) won’t be a ₹5 coin?

Solution:

Complete no. of coins = 100+50+20+10 = 180

P(E) = (Number of ideal results/Total number of results)

(I) Total number of 50 p coin = 100

P (50 p coin) = 100/180 = 5/9 = 0.55

(ii) Total number of ₹5 coin = 10

P (₹5 coin) = 10/180 = 1/18 = 0.055

∴ P (not ₹5 coin) = 1-P (₹5 coin) = 1-0.055 = 0.945
