Mga Hakbang ng Solution

I-multiply ang 0.3 at 0.4 para makuha ang 0.12.

$$0.12\times 0.3+0.7\times 0.7\times 0.4+0.7\times 0.3\times 0.4$$

I-multiply ang 0.12 at 0.3 para makuha ang 0.036.

$$0.036+0.7\times 0.7\times 0.4+0.7\times 0.3\times 0.4$$

I-multiply ang 0.7 at 0.7 para makuha ang 0.49.

$$0.036+0.49\times 0.4+0.7\times 0.3\times 0.4$$

I-multiply ang 0.49 at 0.4 para makuha ang 0.196.

$$0.036+0.196+0.7\times 0.3\times 0.4$$

Idagdag ang 0.036 at 0.196 para makuha ang 0.232.

$$0.232+0.7\times 0.3\times 0.4$$

I-multiply ang 0.7 at 0.3 para makuha ang 0.21.

$$0.232+0.21\times 0.4$$

I-multiply ang 0.21 at 0.4 para makuha ang 0.084.

$$0.232+0.084$$

Idagdag ang 0.232 at 0.084 para makuha ang 0.316.

$$0.316$$

I-factor

$$\frac{79}{2 \cdot 5 ^ {3}} = 0.316$$
