Answer:

the probability is 99.6%

Step-by-step explanation:

The probability of having at least one head is:

[tex]P(x)=1-P(NoHead)[/tex]

The probability of having no heads is given by:

[tex]P(NoHead)=P(tail)^{n}=(\frac{1}{2})^8=\frac{1}{256}[/tex]

so:

[tex]P(x)=1-\frac{1}{256}=\frac{255}{256}=99.6\%[/tex]
