Mean absolute deviation = \(\frac{0+0.02+0.04+0.02}{4}\)
= 0.02
∴ Mean absolute deviation = \(\pm0.02\,mL\)
Relative deviation = \(\frac{Mean\,absolute\,deviation}{Mean}\) x 100%
= \(\frac{0.02}{11.15}\) x 100%
= 0.2%

There are two cases, (i) First digit is greater than 2 (ii First digit is 2
Case : (i) First digit can be chosen from 3,4,5,6 so 4 possibilities, then next 3 digits can be selected from any 6 digits.
= 4 × 6 ×...
There are two restrictions operating this question.
1. For a number to be odd, the unit digit should be either 1,3,5,7 or 9.
2. Thousand can not be filled with 8 or...
