Il-fattorjali ta' 7 huwa 5040.

$$\frac{5040}{1!\left(7-1\right)!}\times 0.6^{1}\times 0.4^{6}$$

Il-fattorjali ta' 1 huwa 1.

$$\frac{5040}{1\left(7-1\right)!}\times 0.6^{1}\times 0.4^{6}$$

Naqqas 1 minn 7 biex tikseb 6.

$$\frac{5040}{1\times 6!}\times 0.6^{1}\times 0.4^{6}$$

Il-fattorjali ta' 6 huwa 720.

$$\frac{5040}{1\times 720}\times 0.6^{1}\times 0.4^{6}$$

Immultiplika 1 u 720 biex tikseb 720.

$$\frac{5040}{720}\times 0.6^{1}\times 0.4^{6}$$

Iddividi 5040 b'720 biex tikseb7.

$$7\times 0.6^{1}\times 0.4^{6}$$

Ikkalkula 0.6 bil-power ta' 1 u tikseb 0.6.

$$7\times 0.6\times 0.4^{6}$$

Immultiplika 7 u 0.6 biex tikseb 4.2.

$$4.2\times 0.4^{6}$$

Ikkalkula 0.4 bil-power ta' 6 u tikseb 0.004096.

$$4.2\times 0.004096$$

Immultiplika 4.2 u 0.004096 biex tikseb 0.0172032.

$$0.0172032$$

Fattur

$$\frac{3 \cdot 7 \cdot 2 ^ {6}}{5 ^ {7}} = 0.0172032$$
