Explanation:

To find the answer in these problems you must first convert the mixed numbers to improper fractions using the equations .

So for the top equation you would have to do something like which equals:

And make sure to do that for both mixed numbers.

You would then plug those mixed numbers back into the equation like so:

Multiply them together to get

then subtract that by 1/2

convert it back into a mixed fraction.

and you should get as your answer.

You then must do that for all the questions and find whichever ones match with that one.

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%
