Explanation:
Given
A coin
--- Number of flips
![x \to heads](https://img.qammunity.org/2022/formulas/mathematics/college/3f9jwxpvt6qk9x62ydpcbfqhejmfzg4ij4.png)
Required
Which can't be the value of x
From the question, we understand that the coin was flipped 7 times.
This means that, the highest occurrence of head is:
![x = 7](https://img.qammunity.org/2022/formulas/mathematics/college/bf53fqeffext1l0o2vdrwy0k70p8jnc19d.png)
And the list is:
![x = 0](https://img.qammunity.org/2022/formulas/mathematics/college/3pyz5m0wu5tdq4d9xpoxatrwmodt9x8yud.png)
So, the range of x is:
![x = \{0,1,2,....,7\}](https://img.qammunity.org/2022/formulas/mathematics/college/d4r1w3vj4rg8hkbnme87x6jb2gqyp8f4kw.png)
In the above range, only (16) is out of range.
Hence:
--- Number of heads can't be 16
