Answer:
True, for Probability of a chance event certain to happen is 1.
Step-by-step 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
lies between
..

When An Event is certain to occur then its
.
when An Event cannot possible to occur then its
.
And
Is there any chance that event will occur then its value lies
.
Let us take an Example:-
- If it is Saturday, then the probability that tomorrow is Sunday is certain, therefore the probability is 1.
- 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.
