Question 1

1.

Jada, Diego, and Elena each use the same spinner that has four (not necessarily equal sized) sections marked A, B, C, and D.

Based on their methods, which probability estimate do you think is the most accurate?

Diego says, "The probability of spinning B is 20% because I spun 5 times, and it landed on B once."

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

Elena says, "The probability of spinning B is 2/7 because I spun 7 times, and it landed on B twice."

Andre measures the spinner and finds that the B section takes up 1/4 of the circle. Explain why none of the methods match this probability exactly.
