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
To find the empirical probability of David's incorrect responses, we first need to find the number of incorrect responses he made.
If he got 45 out of 70 items correct, then the number of incorrect responses would be:
70 - 45 = 25
So, David made 25 incorrect responses out of 70 total items.
The empirical probability of his incorrect responses would be the number of incorrect responses divided by the total number of responses:
25/70
This fraction can be simplified by dividing both the numerator and denominator by the greatest common factor, which is 5.
25/70 = 5/14
Therefore, the empirical probability of David's incorrect responses is 5/14.
