Use the table to answer the question. Numbers a b a + b = 39 Check b = one-half a + 6 20 19 39 22 17 39 24 15 39 26 13 39 20 and 19 22 and 17 24 and 15 26 and 13

hello there buddy

Step-by-step explanation:

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%

you.
