Question

Express the indicated degree of likelihood as a probability value between 0 and $1 .$ When making a random guess for an answer to a multiple choice question on an SAT test, the possible answers are $\mathrm{a}, \mathrm{b}, \mathrm{c}, \mathrm{d}, \mathrm{e}$, so there is 1 chance in 5 of being correct.

Key Concepts

Probability

Probability is a measure of how likely an event is to occur, typically expressed as a number between 0 and 1. This numerical value represents the chance that a particular event will occur, where 0 means the event is impossible and 1 indicates certainty.

Uniform Probability Distribution

A uniform probability distribution refers to scenarios where every outcome in the sample space has an equal likelihood of occurring. It is commonly applicable in situations involving random guessing, where each possible answer is as likely as any other.

Conversion of Fraction to Decimal

Converting a fraction to a decimal is a method of expressing probability in a standard numerical form. This practice enables easier interpretation and comparison of probabilities, as decimals provide a common basis for quantifying chance.
