If:
\(\frac{Boys}{20} = 0.45\)
Soon:
\(\frac{Boys}{20} = 0.45 \to Boys = 20*0.45 \to \boxed{Boys = 9}\)
Therefore: (It's not a boy)
Students = 20
Boys = 9
girls = ?
\(Girls + Boys = Students\)
\(Girls + 9 = 20\)
\(Girls = 20 - 9\)
\(\boxed{Girls = 11}\)
Answer: (Describe the likelihood of not choosing a boy)
\(\frac{11}{20} = \boxed{\boxed{0.55}}\end{array}}\qquad\quad\checkmark\)
