8. a community group orders 1,250 water bottles to donate to the runners in a marathon. if the probability of a water bottle being defective is 1.2%, prdict how many of the water bottles are to be defective. round your answer to the nearest whole number. a) 12 b) 15 c) 130 d) 150

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.
