Solution

## The correct option is B 60Number of trials = 100 The event in this case is a tail appearing on the coin. Let the number of times a tail appeared be X. ∴ The number of trials where the event happened = X We know, for an event E P(E) = Number of trials in which the event happenedTotal number of trials Given, P(E)=0.6 ⟹X100=0.6 ⟹X=60 Hence, a tail would have appeared 60 times.
