To find the empirical probability of David's incorrect responses, we need to divide the number of incorrect responses by the total number of responses.
Total number of responses = 70
Number of correct responses = 45
Number of incorrect responses = 70 - 45 = 25
Empirical probability of incorrect responses = Number of incorrect responses/Total number of responses
Empirical probability of incorrect responses = 25/70
Empirical probability of incorrect responses = 5/14
Therefore, the empirical probability of David's incorrect responses is 5/14.
On a science quiz, David got 45 out of 70 items correct. What is the empirical probability of his incorrect responses? Write your answer in the simplest form of a fraction.(1 point)
