Ko te huarea o 7 ko 5040.

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

Ko te huarea o 1 ko 1.

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

Tangohia te 1 i te 7, ka 6.

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

Ko te huarea o 6 ko 720.

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

Whakareatia te 1 ki te 720, ka 720.

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

Whakawehea te 5040 ki te 720, kia riro ko 7.

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

Tātaihia te 0.6 mā te pū o 1, kia riro ko 0.6.

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

Whakareatia te 7 ki te 0.6, ka 4.2.

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

Tātaihia te 0.4 mā te pū o 6, kia riro ko 0.004096.

$$4.2\times 0.004096$$

Whakareatia te 4.2 ki te 0.004096, ka 0.0172032.

$$0.0172032$$

Tauwehe

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