Let us first evaluate the properties for probability.
00:06
So, for a probability must be always positive.
00:11
That is the first thing we have to keep in our mind.
00:15
That is, p of a is always greater than or equal to 0.
00:18
And the value of p of a must lie between the values 0 and 1.
00:25
And now we can analyze the given values and whether that will become a probability or not.
00:30
The first one is given as 25 by 25 which is equal to 1.
00:34
So this can be a valid probability because 1 is a possible value here.
00:41
And the next 1 it is given as 333 .3 percentage and this will become 333 .3 divided by 100.
00:53
So this will become 3 .33 which is greater than 0.
00:58
So it is the invalid probability.
01:01
This cannot be a probability at all.
01:04
Now, the third one, it is given us 2 .3.
01:08
Here also, this is clearly greater than what.
01:10
So it is invalid probability...
