Question

Which one is a known outcome.​

Answer 1

Answer:

An outcome is the result of a single trial of an experiment.

Rolling a pair dice cannot be an outcome, cause it results in 36 outcomes, but it can be an experiment.

Landing on red is an outcome as after performing an experiment, the result can be landing on red.

Choosing 2 marbles from a jar cannot be an outcome, because it is not known how many balls are there, but it can be an experiment.

Answer 2

Answer:

an outcome is a possible result of an experiment or trial.[1] Each possible outcome of a particular experiment is unique, and different outcomes are mutually exclusive (only one outcome will occur on each trial of the experiment). All of the possible outcomes of an experiment form the elements of a sample space.[2]

For the experiment where we flip a coin twice, the four possible outcomes that make up our sample space are (H, T), (T, H), (T, T) and (H, H), where "H" represents a "heads", and "T" represents a "tails".
