Answer»

(b) 0.0125

Given exp.

= \(\frac{0.1\times0.1\times0.1 + 0.02\times0.02\times0.02}{8(0.1\times0.1\times0.1)+8(0.02\times0.02\times0.02)} \)

= \(\frac18\bigg(\frac{0.1\times0.1\times0.1 + 0.02\times0.02\times0.02}{0.1\times0.1\times0.1+0.02\times0.02\times0.02}\bigg)\)

= \(\frac18\) = 0.0125.
