Mathematics

$E(x)=\$9.118$

Step-by-step explanation:

From the question we are told that:

Available bills

$\$5=N0 9\\\\\$10=N0 5$

$\$20=N0 3$

Therefore

Total Bills

n=5+9+3

n=17

Probability of selecting each bill

$For\$5$

$P(\$5)=\frac{9}{17}$

$For\$10$

$P(\$10)=\frac{5}{17}$

$For\$20$

$P(\$20)=\frac{3}{17}$

Generally the equation for Expected winning is mathematically given by

$E(x)=\sum(X)*P(X)$

$E(x)=5*\frac{9}{17}+10*\frac{5}{17}+20*\frac{3}{17}$

$E(x)=\$9.118$
