Answer #1

Statistics software output:

f(x) 0.47 0.31 0.2+ 0.11 10AŹ Mean: 0 P( -1.22 Std. Dev.: 1 sxs 2.22 ) = 0.87555818 Compute

But here it is asking area outside these limit so the required area = 1 - 0.87556 = 0.12444

We need to round to 4 decimal places hence the answer is 0.1244

Please comment if any doubt. Thank you.
