Question -
Answer -
Given: A coin is tossed.
When a coin is tossed, there will be two possible outcomes, Head (H) and Tail (T).
Since, the no. of elementary events is 2 {H, T}
We know, if there are n elements in a set, then the number of total element in its subset is 2n.
So, the total number of the experiment is 4,
There are 4 subset of S = {H}, {T}, {H, T} and Փ
∴ There are total 4 events in a given experiment.
