Answer:
Option B.
Step-by-step explanation:
It is given that,
Number of $1 bills = 5
Number of $5 bills = 4
Number of $10 bills = 6
Number of $20 bills = 3
So,
Total number of bills = 5 + 4 + 6 + 3 = 18
We need to find the probability of a 1 then a ten (without replacement).
Probability of selecting $1 bill in first draw
After one draw, the number of remaining bills is 18 - 1 = 17.
Probability of selecting $10 bill in second draw
The probability of a 1 then a ten is
Therefore, the correct option is B.
