Event is called performing an experiment once

Answer 2

Performing an event once is called an experiment .

Explanation :

• In probability , any event which could have a possible outcome from a calculated set of outcomes and for which we cannot already predict the result is called a random experiment .
• For example , picking a card from a pack of card , this is or will be a random experiment because we cannot predict the result beforehand.
• Another example is tossing a coin , although the probability of getting head or tail is equal that is 0.5 still such experiments shall be called a event .
• Also , an experiment whose outcome is not likely like probability of getting a Tuesday after a Friday is highly unlikely and hence such events are called impossible events.
