To answer this question we will use the z-score.
Recall that the z-score is given as follows:

The z-score of 54 is:

The z-score of 56 is:

Now, the probability of flipping 54, 55, or 56 heads is the same as the following probability:
![P(0.8Now, recall, that:[tex]P(aNow, from the given table we get that:[tex]\begin{gathered} P(0.8)=0.7881, \\ P(1.2)=0.8849. \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/q3a69aibwzolxwz4a49w0an2vwaq8z0olb.png)
Therefore:
[tex]\begin{gathered} P(0.8
Answer: 0.10.
