According to the empirical rule, for a distribution that is symmetrical and bell-shaped(in particular, for a normal distribution) approximately of the data values will be within two standard deviations on each side of the mean

select one:

a. 75%

b. 95%

c. 68%

d. 99.7%

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.
