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

Elena says, "The probability of spinning B is 27 because I spun 7 times, and it landed on B twice."

b. Andre measures the spinner and finds that the B section takes up 14 of the circle. Explain why none of the methods match this probability exactly.
