Step-by-step explanation:

$-1\frac{2}{7} = -\frac{9}{7}$

-2/3 ÷ -9/7 = 2/3 ÷ 9/7 = 2/3 × 7/9

The probability that the arrow will land on any of them once is 1/4.

The probability that the arrow will land on any of them twice is 1/4 * 1/4. This is because the probability of Event A and Event B is P(B) * P(A).

Based on this:

$P(a\cap b\cap c\cap d) = \frac{1}{4}\times \frac{1}{4}\times\frac{1}{4}\times\frac{1}{4}\\\\=\frac{1}{4\times4\times4\times 4}\\=\frac{1}{256}$

1/256

Hope this helps, let me know if I missed anything!
