A trial is one performance of a chance experiment or repeated procedure.
Continue from this idea into connected AXIO math.
One go, one recorded outcome.
Boundary: Twelve rolls are twelve trials, not one trial with twelve separate outcomes.
What it means
One go is one trial. Roll once, toss once, spin once, or draw once: each go gives one outcome. Repeating the same process gives more trials, which lets you compare results and estimate probabilities.
Remember it
One go, one recorded outcome.
Example
A number cube is rolled 12 times. The seventh roll is one trial, and its outcome might be 4. The whole experiment contains 12 trials.
Watch for
Twelve rolls are twelve trials, not one trial with twelve separate outcomes.
Common mix-up
In probability, a trial is one go of the process—not a court case or a free test period.
Exact meaning
A trial is one performance of a stated chance experiment or repeated procedure. It is carried out under the stated conditions and produces one recorded outcome.
