On a science quiz David got 45 out of 70 items correct. What is the empirical probability of his incorrect responses? Write the answer in the simplest form of a fraction
To find the probability of his incorrect responses, we first need to find the number of incorrect responses.
David got 45 out of 70 items correct, so the number of incorrect responses would be 70 - 45 = 25.
Therefore, the probability of his incorrect responses is 25/70, which simplifies to 5/14.
So, the empirical probability of his incorrect responses is 5/14.
