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:

The number of favorable outcomes is the number of choices (such as rolling a two on a die) and the probability is found by comparing this to the total number of outcomes (six in the case of a die). Arithmetic can be used to calculate outcomes. Let's look at an example.
