All the events in the sample space that are not part of the specified event are called

a. simple events

b. joint events

c. independent events.

d. the complement of the event.

All the events in the sample space that are not are the part of the specified event are All called the complement of the event.

Step-by-step explanation:

Suppose tossing a coin, the sample space here is {H, T}.

Now, if the event is getting a head,

so here T is not the part of the sample space and is called as complement of the event.

Therefore, all the events in the sample space that are not are the part of the specified event are All called the complement of the event.
