Step-by-step explanation:

convert 2 1/2 hours into minutes to be easier to work with

15 / 150 = 10 minutes

every 10 minutes he pots a plan.

there are 210 minutes in 3 1/2 hours

210 / 10 = 21  

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%
