2. after a coin is flipped 80 times, the relative frequency of tails is 0.5. the coin is flipped one more time. what are the possible relative frequencies of tails after flipping the coin 81 times? select all that apply.

Answer

Explanation:

Step1: Calculate initial number of tails

$$80 \times 0.5 = 40$$

Step2: Consider the 81st flip as heads

$$\frac{40 + 0}{81} \approx 0.4938$$

Step3: Consider the 81st flip as tails

$$\frac{40 + 1}{81} \approx 0.5062$$

Answer:

$\frac{40}{81}$ (approximately 0.4938) and $\frac{41}{81}$ (approximately 0.5062)
