<span>
u need two equations.</span><span>x + y = 125
0.60x + 0.30y = (0.36)(125)</span>
<span /><span>x + y = 125
0.60x + 0.30y = 45</span>
<span>solve for a variable in the first equation
y = 125 - x</span>
<span>plug into the second equation
0.60x + 0.30(125 - x) = 45
0.60x + 37.5 - 0.30x= 45
0.30x + 37.5 = 45
0.30x = 7.5
x = 25</span>
<span>plug the answer for x into the first equation
25 + y = 125
y = 100</span>

If the coins are selected without replacement, the probability of 2 dimes is:
![\frac{5}{8}\times\frac{4}{7}=\frac{5}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7D%5Ctimes%5Cfrac%7B4%7D%7B7%7D%3D%5Cfrac%7B5%7D%7B14%7D)
The answer is 5/14.
Using the formula for a hypergeometric distribution, we get:
