Answer :
Answer:
5/ 14
Step-by-step explanation:
David got 45 out of 70 items correct, means that David's incorrect responses are 25 out of 70.
Therefore,
The empirical probability of his incorrect responses = number of incorrect responses ÷ total responses
= 25 / 70
= 5/ 14
Empirical probability is probability based on experience. So if you flipped a coin three times and got heads every time, the empirical probability of getting heads again would be 100%.
In this case, the empirical probability of the number of incorrect responses is directly related to David's experience. According to that reasoning, he will get 25/70 questions wrong next time. Reduced that is 5/14.
This question IS worded a little weirdly, so getting confused is completely normal. Before submitting, make sure you agree with everything I say. If it makes sense to you too, then its probably right.
