Step-by-step explanation:

Refer to photo for everything. Also, I didn’t do a lot of the algebraic steps on paper; try to do it yourself and see if you can get what I got. But, I did write out the process of finding the answer. I checked the answer with what was given and everything seems to work, but you should check yourself before using this answer just in case.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
