I need help with this question-

B

Step-by-step explanation:

if the circle is colored in then it would greater/less than or equal too. Think of it as friends, if you don't like them you don't wanna touch them so therefore it'd be an open circle, but if you like them and want to include them it would be a closed circle

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.
