TheseGiven the set: {-18, -16, -14, -12, -10, -8, -6}
This is 7 numbers
Multiplies of -6 are:
[tex]\begin{gathered} -6\times1=-6 \\ -6\times2=-12 \\ -6\times3=-18 \end{gathered}[/tex]This is 3 numbers
Therefore, the probability is given by:
[tex]P=\frac{multiplies\text{ of }-6}{total\text{ set }}[/tex]So:
[tex]P=\frac{3}{7}[/tex]Answer: 3/7
