The estimate of 5/8 - 4/7 would be closest to 0.
If a spinner with 5 sections and the spinner is currently on 5 is spun twice, what is the probability that both spins result in a 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.
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.
Therefore, 3^-4 = 1/81.
