Answer:
![\frac{4}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B21%7D)
Step-by-step explanation:
Another way of phrasing this question is this; if only two bills are selected without replacement, what is the probability that at one of the two bills will be a $10 bill:
P(One $10 bill) = P(picking a $10 bill first then another type) + (picking another
type then a $10 bill)
= ![\frac{5}{15}*\frac{10}{14}+\frac{10}{15} *\frac{5}{14} = \frac{4}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B15%7D%2A%5Cfrac%7B10%7D%7B14%7D%2B%5Cfrac%7B10%7D%7B15%7D%20%2A%5Cfrac%7B5%7D%7B14%7D%20%3D%20%5Cfrac%7B4%7D%7B21%7D)
Answer:
4n + 5
Step-by-step explanation:
This equation cannot be simplified further
Unless you meant 4n + 7 <em>=</em> 2
Then the answer would be -1.25
Answer:
As a fraction? If so, it would be 4/9.
Step-by-step explanation:
To find this answer, you must know that 8 and 18 can both be divided by 2. Which would be 4 and 9. Therefor, you have your answer: 4/9
