Answer: Probability of twenty- dollar bill is 0.
Step-by-step explanation:
Number of five dollars = 2
Number of ten dollars = 9
Total number of dollars is given by
[tex]2+9=11[/tex]
Since there is no twenty dollar bills.
So, Probability of getting twenty- dollar bill is given by
[tex]\frac{\text{ Number of favourable outcomes}}{\text{ total number of outcomes}}\\\\=\frac{0}{11}\\\\=0[/tex]
Hence, Probability of twenty- dollar bill is 0.
