Please help me

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.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
