Answer: Fraction of the trees will be Oak Willow or pine is given by
[tex]\frac{3}{5}[/tex]
Step-by-step explanation:
Since we have given that
Part of the park department is Oak is given by
[tex]\frac{1}{10}[/tex]
Part of the park department is Pine is given by
[tex]\frac{3}{10}[/tex]
Part of the park department is Willow is given by
[tex]\frac{2}{10}[/tex]
Total fraction of the trees will be Oak , Willow, Pine is given by
[tex]\frac{1}{10}+\frac{3}{10}+\frac{2}{10}\\\\=\frac{1+3+2}{10}\\\\=\frac{6}{10}\\\\=\frac{3}{5}[/tex]
Hence, Fraction of the trees will be Oak Willow or pine is given by
[tex]\frac{3}{5}[/tex]
