I'm not sure yet...but this is half of it

Step-by-step explanation:

7+2=9 360÷9=40

40×7=280

40×2=80

40×3=120-80=60

sorry...but hope that helps

a = 11 : 4

b = 38

c = 1 for every 6

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.
