There are 10 pairs of shoes. 8 shoes are select.
<span>P = (2/20) (2/19) (2/18) (2/17) (2/16) (2/15) (2/14) (2/13) </span>
<span>P = 2^8 / (20P8) </span>
<span>But, any 8 differents shoes can be chosen from 10 pairs. </span>
<span>so there are 10C8 = 45 ways to do so </span>
<span>P = 45 * 2^8 / (20C8) </span>
<span>But, since order does not matter, there are 8! way you can select the 8 different shoes </span>
<span>P = 8! * 45 * 2^8 / (20C8) </span>
<span>P = 384/4199 or about 9.145%</span>

Answer:
1. x= -b/a
2. x=b/a+c
3. x=b/a
4. x=a/-b+c
5. x= -a/b
6. x=c/a+b
7. x= -c/a+b
8. x=c/a-b
9. x=-b/c
10. x=a/b+c
11. x=c/-a+b
12. x= -c/b
13. x=a/-b+c
14. x= -c/a+b
15. x= -a/b+c
16. x=-a/-b+c
17. x= c/a+b
18. x= -c/a-b
19. x= -b/a+c
20. x=b/a+c
