Probability Problem

 
Label equal sections of a spinner "," "," "-12," "8.2," "," "," "," "."

Find the probability of each outcome.

  • P(spinning a rational number)
  • P(spinning an integer)
  • P(spinning a whole number)
Use the probability for spinning an integer to predict the number of times an integer will be spun in twenty-five, fifty, and one hundred spins. Then perform the experiment. Write the number of successful outcomes out of each number of spins as a fraction and as a decimal. What can you say about using probability to predict actual events?
