Me solve this question, "you answer 16 out of 20 questions correctly on a test. your friend answers 25 out of 30 questions correctly on a different test. who has the better score? "

Step-by-step explanation:

You answer 16 out of 20 questions correctly on a test. Number of questions unanswered is

20 - 16 = 4

The percentage of questions that you answered will be number of questions answered / total number of questions × 100

It becomes

16/20 × 100 = 80%

Your friend answers 25 out of 30 questions correctly on a different test. Number of questions unanswered is 30 - 25 = 5

The percentage of questions that your answered will be number of questions answered / total number of questions × 100

It becomes

25/30 × 100 = 67.67%

Comparing the percentages, your percentage was higher. It means that you had the better score.

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%
