Probability, Sample Space

Probability is a measure of how likely an event is to occur, expressed as a number between 0 (impossible) and 1 (certain).

A sample space is the set of all possible outcomes of a probability experiment.

The possible outcomes are 1, 2, 3, 4, 5, and 6.

The probability is 3/6 or 1/2, since the even numbers are 2, 4, and 6.

'Equally likely' means that all outcomes have the same chance of occurring.

Use the formula 2^n, where n is the number of coins. For example, 2^4 = 16 outcomes for 4 coins.

The fundamental counting principle states that if one event can occur in m ways and a second can occur independently in n ways, then the two events can occur in m x n ways.

You can make 3 x 2 = 6 outfits.

The probability is 26/52 or 1/2, since there are 26 red cards.

'Impossible' means that the event cannot happen, with a probability of 0.
