on a science quiz, David got 45 out of 70 items correct. What is the empirical probability of is incorrect responses? write your answer in the simplest form of a fraction.
To find the empirical probability of David's incorrect responses, subtract the number of correct responses from the total items answered:
70 total items - 45 correct responses = 25 incorrect responses
So, the empirical probability of David's incorrect responses is 25/70, which can be simplified to 5/14.
