Question

A coin is tossed once and we get a head on the coin. Which of the following is/are true?

• A. The tossing of the coin is an event.
• B. Each toss of the coin is a trial.
• C. The getting of a head is a trial.
• D. The getting of a head is an event.

Answer 1

Answer: (B), (D)

The correct options are
B Each toss of the coin is a trial.
D The getting of a head is an event.

In this experiment of tossing a coin:

• each toss of a coin is called a trial.

(A trial is an action which results in one or several outcomes. The possible outcomes in the above mentioned trial were head and tail.)

• the getting of a head in a particular throw is an event with outcome ‘head’

(An event for an experiment is the collection of some outcomes of the experiment. Hence, the event in this case was getting of a head.)
