Ko te huarea o 7 ko 5040.

$$\frac{5040}{0!\left(7-0\right)!}\times 0.6^{0}\times 0.4^{7}$$

Ko te huarea o 0 ko 1.

$$\frac{5040}{1\left(7-0\right)!}\times 0.6^{0}\times 0.4^{7}$$

Tangohia te 0 i te 7, ka 7.

$$\frac{5040}{1\times 7!}\times 0.6^{0}\times 0.4^{7}$$

Ko te huarea o 7 ko 5040.

$$\frac{5040}{1\times 5040}\times 0.6^{0}\times 0.4^{7}$$

Whakareatia te 1 ki te 5040, ka 5040.

$$\frac{5040}{5040}\times 0.6^{0}\times 0.4^{7}$$

Whakawehea te 5040 ki te 5040, kia riro ko 1.

$$1\times 0.6^{0}\times 0.4^{7}$$

Tātaihia te 0.6 mā te pū o 0, kia riro ko 1.

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

Whakareatia te 1 ki te 1, ka 1.

$$0.4^{7}$$

Tātaihia te 0.4 mā te pū o 7, kia riro ko 0.0016384.

$$0.0016384$$

Tauwehe

$$\frac{2 ^ {7}}{5 ^ {7}} = 0.0016384$$
