Probability can be expressed as a ratio, a fraction, or a decimal.
For example if there are 4 red balls and 4 white balls in a bucket and you pick one without looking the probability (chance) that you will pick a red ball is a half, because half the balls are that colour.
You can say that the probability of that happening is 1/2 or 50% or 0.5
The probability is the same for choosing a white ball.

There is a fourth way, and that is in the form of odds.

What is the equation used to determine probability in what ways can probability be expressed?
Probability = number of times an event is expected to happen / number of opportunities for an event to happen It can be expressed as a percentage or a fraction.
What are the three ways probabilities are expressed?
Fractions can be expressed as any of fractions, decimals or percentages. Which of the above is normally governed by personal preference, the standard for the medium of communication, and the nature of the information.
What are three ways to express probability?
percentage, decimal, fraction
Can probability be expressed as a percent?
Yes, probability can be expressed as a percent. It is common to express probabilities as a percentage, which is calculated by multiplying the probability by 100. For example, if the probability of an event is 0.25, it can also be expressed as 25%.
How can probability be expressed?
The probability of an event is a number in the interval [0, 1]. It can be expressed as a fraction or ratio or as a percentage. Furthermore, if the probability of an event is p, where 0<p<1, and if q = 1-p, then the probability of the event can also be expressed as odds of p to q in favour.
