Question

Jada, Diego, and Elena each use the same spinner that has 4 sections marked A, B, C , and D. Which estimate do you think is most accurate? Jada says, "The probability of spinning B is 0.3 because I spun 10 times, and it landed on B 3 times. " Diego says, "The probability of spinning B is 20% because I spun 5 times, and it landed on B twice." Elena says, "The probability of spinning B is 2/7 because I spun 7 times, and it landed on B twice."

Answer 1

The correct option is;

"The probability of spinning B is 0.3 because I spun 10 times, and it landed on B 3 times."

Explanation:

Out of the three trials, Jada had the most number of trials (10) and therefore, the highest precision value and the best estimate out of the three persons that did the trials

The more the sample or trials increase, the more the precision increases as the number of trial comparisons and testing increases.

The increased trials give more information, resulting in a more precise estimate. It also increases the confidence in the result and reduces the amount of uncertainty and increases precision of the results.
