The estimate of 5/8 - 4/7 would be closest to 0.
Answered by GPT 3.5
The probability of spinning a 5 on each spin is independent, so we can multiply the individual probabilities.

The probability of spinning a 5 on the first spin is 1/5.
The probability of spinning a 5 on the second spin is also 1/5.

Therefore, the probability of spinning a 5 on both spins is (1/5) * (1/5) = 1/25.

3^-4 is the same as 1/(3^4), which is equal to 1/(3*3*3*3) = 1/81.

Therefore, 3^-4 = 1/81.
