Question

A chance event with probability 1 is certain to happen.

True or False?

There was a hint and it said;

The probability of a chance event is a number between 0 and 1.

Answer 1

Answer: It would be true. 100%

Explanation:

Answer 2

True, for Probability of a chance event certain to happen is 1.

Explanation:

Given that,

A chance of event with probability of happening certainly is 1.

To find:- Is it true or false?

from the given scenario,

Probability states that P(Event) is a number describing the chance of that event will happen And value of
`P(E)` lies between
`0\leq P(E)\leq 1`..

`P(An Event) =`
`(Number of favourable outcomes)/(Total number of outcomes)`

When An Event is certain to occur then its
`P(E) = 1`.

when An Event cannot possible to occur then its
`P(E) = 0`.

And

Is there any chance that event will occur then its value lies
`0\leq P(E)\leq 1`.

Let us take an Example:-

1. If it is Saturday, then the probability that tomorrow is Sunday is certain, therefore the probability is 1.
2. The probability that tomorrow is Friday if today is Sunday is 0.

Hence,

True, for Probability of a chance event certain to happen is 1.
