When flipping a fair coin, the probability of getting tails on each flip is 0.5. If Joe flips the coin 8 times, the expected number of tails can be calculated as follows:
\[
\text{Expected number of tails} = \text{Number of flips} \times \text{Probability of tails} = 8 \times 0.5 = 4.
\]
Therefore, the best prediction for the number of times it will land on tails after 8 flips is **4**.
\[
\text{Expected number of tails} = \text{Number of flips} \times \text{Probability of tails} = 8 \times 0.5 = 4.
\]
Therefore, the best prediction for the number of times it will land on tails after 8 flips is **4**.
