Question
Tossing a coin is ___ event
- Equally likely
- Unequally likely
- Certain
- random
Hint:
In probability, an event is a set of outcomes of an experiment to which a probability is assigned.
The correct answer is: Equally likely
Here, we have to tell what kind of event is tossing a coin.
When a coin is tossed, outcomes are Head and Tail.
Total outcomes = 2
P ( Head ) = 1/2 , and P ( Tail) = 1/2
Since, both events have the same probability and any one event can happen at random.
Therefore, tossing a coin is a random event.
Hence, the correct option is (d)
A random event is an event in which any outcome of all the possible one can occur.
