Introduction to Probability: Experiments, Sample Space, Simple Events and Outcomes

What is probability?

Probability is a branch of mathematics that studies uncertainly and chance. It deals with predicting possible outcomes of random events and is widely used in statistics, science, and real-life decision-making. In short probability is measure of chance.

EXPERIMENT

An experiment is an

action or process that

leads to an outcome

but the results cannot

be precisely predicted

OUTCOME

Outcome is a

possible result of a

single trial of an

experiment

OUTCOME

Outcome is a

possible result of a

single trial of an

experiment

Sample Space (s)

Sample Space is the

set of all possible

outcomes in an

experiment

Event

One or more outcomes

of an experiment, a

subset of the sample

space.

Activity: Identify the experiment, outcome, sample space, and event in the following situations.

1. A spinner consists of 3 colors: blue, red, and yellow. When spun, the result is blue. a. Experiment: b.Outcome: c. Sample Space: d.Event:
