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)
Answer
Explanation:
Step1: Calculate number of incorrect responses
Total items = 70, Correct items = 45. Incorrect items = 70 - 45 = 25.
Step2: Calculate empirical probability
Empirical probability = $\frac{\text{Number of incorrect responses}}{\text{Total number of responses}}$. So, probability = $\frac{25}{70}$.
Step3: Simplify the fraction
$\frac{25}{70}=\frac{25\div5}{70\div5}=\frac{5}{14}$.
Answer:
$\frac{5}{14}$
