When rolling one die, there is one "5" outcome and six total outcomes. The formula for probability is represented as:
[tex]P(A) = \dfrac{\textrm{number of outcomes resulting in} \,A}{\textrm{total number of outcomes}}[/tex]
Thus in this case, to find [tex]P(5)[/tex], we would go about the following:
[tex]P(5) = \dfrac{1}{6}[/tex]
To convert [tex]\frac{1}{6}[/tex] to a percent, we first multiply by 100 and then divide, as shown:
[tex]\dfrac{1}{6} \cdot 100 = \dfrac{100}{6} = 16.\overline{6} \,\%[/tex]
The fraction would be 1/6 and the percentage would be 16.666...%, which is often rounded to 16.67%.
