[tex] \frac{1}{400 } \\ [/tex]
Explicación paso a paso:
[tex] \frac{1}{4} \times \frac{1}{4} \times \frac{1}{5} \times \frac{1}{5} = \frac{1 \times 1 \times 1 \times 1}{4 \times 4 \times 5 \times 5} = \\ [/tex]
[tex] \frac{1 \times 1}{4 \times 4 \times 5 \times 5} = \frac{1}{4 \times 4 \times 5 \times 5} = \frac{1}{16 \times 5 \times 5} = [/tex]
[tex] \frac{1}{80 \times 5} = \frac{1}{400} \\ [/tex]
