a spinner is divided into six equal parts numbered 1, 2, 3, 4, 5, 6. In a repeated experiment, Ryan spun the spinner twice. The theoretical probability of both spins being even numbers is 9/36. If the experiment is repeated 200 times, predict the number of times both spins will be even numbers

Answer:

  50

Step-by-step explanation:

You want the expected number of outcomes that result in 2 even numbers if the theoretical probability is 9/36 and the experiment is repeated 200 times.

Expected value

The expected number is the product of the theoretical probability and the number of times the experiment is repeated:

  (9/36)·200 = 200/4 = 50

The number of times both spins will be even is expected to be 50.
