Probability Likely Unlikely Certain Impossible Equally Likely Events Example

Probability Likely Unlikely Certain Impossible Equally Likely Events Example. Certain likely, unlikely, impossible, likely and equally likely events. In this video, you will learn, what are certain or sure events? What are the likely events? What are the impossible events? What are equally likely events? The probability of an event is a measure of the likelihood, or chance, that the event will occur. Probability is a number from 0 to 1, including 0 and 1, and can be expressed as a decimal, fraction, or percent. If the probability of an event is 0, it is said impossible to happen. Numerically it can be expressed by 0 or 0%. If the probability of an event is one-quarter, then it called an unlikely event. Numerically it can be expressed by 0.25 or 25%. If the probability of an event is one-half, then it called equally likely to happen or not happen. Numerically it is expressed as 0.5 or 50%. If the probability of an event is three-quarters, then it is called a likely event. Numerically it is expressed as 0.75 or 75%. Lastly, if the probability of an event is 1, then it is called a certain event. Numerically it is denoted by 1 or 100%.
