Answer:
the probability that the rack ends up in alphabetical order is 0.0001984
Step-by-step explanation:
Given that:
You own 24 CDs. You want to randomly arrange 7 of them in a CD rack.
Th probability that the rack ends up in alphabetical order can be determined by taking note of the permutations and combinations.
From above; all possible permutations of size 7 we can derive from 24 is
24P7
Similarly,we are meant to estimate all the possible ways a unique set of 7 things can be gotten from a total of 24
i.e
24 C7
∴
The probability = 
= 
=
= 
= 0.0001984
the probability that the rack ends up in alphabetical order is 0.0001984
D+q=38
0.1d+0.25q=5.75
Multiply the second equation by -10 and use elimination method.
-d-2.5q=-57.5
d+q=38
-1.5q=-19.5
q=13
Plug quarter number in
d+13=38
d=25
Final answer: 13 quarters, 25 dimes
