Find by referring to the tree diagram and using Bayes' formula. A tree diagram has a root labeled Start that splits into 3 primary branches labeled U, V, and W. Starting from the top, the paths to the primary branches are labeled 0.1, 0.3, and 0.6. Each primary branch splits into 2 secondary branches, labeled C and C'. Starting from the top, the paths to the secondary branches are labeled 0.9, 0.1, 0.3, 0.7, 0.6, and 0.4.

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%
