Question

During an experiment, a spinner landed on green 9 times, which resulted in an experimental probability of 1/6. Mary said that there must have been 45 trials in the experiment. Why is Mary incorrect?

Answer 1

Its A ----------------------------------------

Answer 2

because if there was 45 trials, and u landed on green 9 times...the resulting probability would be 9/45 which reduces to 1/5, not 1/6.

however, if there were 54 trials, and u landed on green 9 times...the resulting probability would be 9/54 which reduces to 1/6.
