a. 1/15
b. 1/5
c. 4/15
d. 2/5 **
Answered by Steve
you are correct.
Answered by Ms. Sue

is 2/5 correct?

Yes, 2/5 is correct.

To get this answer, you need to find the probability of picking a $20 bill by subtracting the probability of picking a $5 bill and the probability of picking a $10 bill from 1 (since these are the only three options).

So, 1 - 1/3 - x = 4/15, where x is the probability of picking a $10 bill.

Solving for x, you get x = 1/15.

Then, the probability of picking a $20 bill is 4/15 - 1/15 = 3/15 = 1/5.
