Question

What does likely mean in probability?

Answer 1

Likely mean in probability:

• A probability is the chance of an event to occur.

$\mathit{P}\left(aneventoccurs\right)\mathbf{=}\frac{\mathbf{N}\mathbf{u}\mathbf{m}\mathbf{b}\mathbf{e}\mathbf{r}\mathbf{}\mathbf{o}\mathbf{f}\mathbf{}\mathbf{f}\mathbf{a}\mathbf{v}\mathbf{o}\mathbf{r}\mathbf{a}\mathbf{b}\mathbf{l}\mathbf{e}\mathbf{}\mathbf{o}\mathbf{u}\mathbf{t}\mathbf{c}\mathbf{o}\mathbf{m}\mathbf{e}\mathbf{s}}{\mathbf{T}\mathbf{o}\mathbf{t}\mathbf{a}\mathbf{l}\mathbf{}\mathbf{n}\mathbf{u}\mathbf{m}\mathbf{b}\mathbf{e}\mathbf{r}\mathbf{}\mathbf{o}\mathbf{f}\mathbf{}\mathbf{o}\mathbf{u}\mathbf{t}\mathbf{c}\mathbf{o}\mathbf{m}\mathbf{e}\mathbf{s}}$

• If the event is "likely to occur, there are great chances that the event occurs.
• The total probability is always equal to unity.
• If the event is “certain” to happen, the probability will be $1$.
• If the event is “likely” to happen, the probability will be between $\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$ and $1$.
• If the event has an “equal chance” to happen or not, the probability will be $\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$.
• If the event is “unlikely” to happen, the probability will be between $0$and $\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$.
• If the event is “impossible” to happen, the probability will be $0$.

Hence, the meaning of ‘ likely ’ is explained.
