For this question, chip -shift inequality is given here.
00:05
So for a value of k and here, we have this thing.
00:14
So, m is the main of the random variable, and sigma is a standard deviation of the random variable, and k is positive here.
00:25
So k is positive number.
00:27
And here for the first question, we have main.
00:30
Is 30 and then deviation is 4.
00:33
Of course, the variance is 16.
00:35
So using trapechef inequality, we will get this.
00:40
Here, we just need to separate this sigma out...
