These question have 5 choices so I have 20% chance of getting right.
What is my chance of getting 24 or more right?

Maybe try to improve your odds by assuming that each letter or number a.b.c.d.e or 1,2,3,4,5, will be used approximately an equal number of times as correct answers. After determining which letters or numbers were used the most in the 10 correct answers, select the remainder from those less used. You may be able to tell from this that my test taking skills could use some improvement.
