Total no. of coins = 100 + 50 + 20 + 10 = 180
Total no. of coins = 100 + 50 + 20 + 10 = 180P(E)
= (Number of favourable outcomes/ Total number of outcomes)
(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
