The correct option is B All of these
If an unbiased coin is tossed once, then the two events of getting a Head and a Tail are Mutually exclusive,Exhaustive,Equally likely
1.Events are said to be equally likely if there is no preference for a particular event over the other.example:
When a coin is tossed, Head (H) or Tail is equally likely to occur.
2.Two or more than two events are said to be mutually exclusive if the occurrence of one of the events excludes the occurrence of the other
example:When a coin is tossed, we get either Head or Tail. Head and Tail cannot come simultaneously. Hence occurrence of Head and Tail are mutually exclusive events.
3.Exhaustive Event is the total number of all possible outcomes of an experiment.
Examples:When a coin is tossed, we get either Head or Tail. Hence there are 2 exhaustive events.
