Question

FIND P(NOT 6) WHEN YOU ROLL A STANDARD NUMBER CUBE THEN DESCRIBE THE LIKELIHOOD OF THE EVENT WRITE IMPOSSIBLE ,UNLIKELY , EQUALLY LIKELY , LIKLEY OR CERAIN

Answer 1

Answer: LIKLEY

Explanation:

Formula : Probability
`=\frac{\text{Number of favorable outcomes}}{\text{Total outcomes}}`

A standard cube has six numbers on it (1,2,3,4,5 and 6).

P( NOT 6) =
`\frac{\text{Numbers that are not 6}}{\text{Total numbers}}`

`=(5)/(6)=0.8333`

We know that when the probability of any event lies between 0.5 and 1then the event is said to be likely to happen.

Since , P(not 6)=0.8333 which lies between 0 and 0.5.

That means, it is likely to happen.

Note :

When probability of having A = 0 , we call A as uncertain event.

When probability of having A = 1 , we call A as certain event.

When probability of having A = 0.5 , we call A as equally likely event.

When probability of having A lies between 0 and 0.5 , we call A as unlikely event.

When probability of having A lies between 0.5 and 1 , we call A as likely event.
