Question

Walter is conducting an experiment using a spinner with 4 equal sections. Which number of trials will lead to experimental outcomes that are most similar to his predicted outcomes? A.4 B.25 C.40 D.90

Answer 1

Option A is correct.

The number of trials that will lead to experimental outcomes that are most similar to his predicted outcomes = 4

Explanation:

The spinner has 4 equal sections. This means that each section has an equal chance of turning out.

The probability that each section of the spinner turns up = (1/4) = 0.25

And the predicted outcomes include each of the section of the spinner

So, spinning the spinner 4 times, theoretically means that each possible outcome will appear once.

Hence, the number of trials that will lead to experimental outcomes that are most similar to his predicted outcomes = 4

Hope this Helps!!!
