Final answer:

The margin of error for LeAnn's estimated probability is approximately 0.192 or 19.2%.

Step-by-step explanation:

To estimate the probability of getting a head with her lucky coin, LeAnn counted the number of heads she got out of 14 flips.

She got 6 heads, so her estimated probability of getting a head is 6/14.

To find the margin of error for LeAnn's estimated probability, we need to use the formula:

Margin of Error = (1 / √n) × √(p × (1-p))

( where n is the number of trials and p is the estimated probability).

Substituting the values, Margin of Error

= (1 / √14) × √(6/14 × (1-6/14))

Simplifying the expression, the margin of error is approximately 0.192 or 19.2%.
