(i) ∵ Total number of possible outcomes = 80
and, the number of favourable outcomes of getting a tail = 80 - 38 = 42
∴ Probability of getting a tail = Number of favourable outcomes/Total number of outcomes
= 42/80 = 21/40
(ii) ∵ Total number of possible outcomes = 80
and, the number of favourable outcomes of getting head = 38
∴ Probability of getting a head = Number of favourable outcomes/Total number of outcomes
= 38/80 = 19/40
