During an experiment, a spinner landed on green 9 times, which resulted in an experimental probability of StartFraction 1 over 6 EndFraction. Mary said that there must have been 45 trials in the experiment. Why is Mary incorrect?
If there were 9 occurrences and 45 trials, the simplified experimental probability would be One-fifth, not StartFraction 1 over 6 EndFraction.
Mary multiplied the 9 occurrences by 6 instead of 5.
Mary mistakenly thought that StartFraction 1 over 6 EndFraction was the simplest form of StartFraction 9 over 45 EndFraction.
If there were 9 occurrences, the simplified experimental probability would be StartFraction 1 over 7 EndFraction, not StartFraction 1 over 6 EndFraction.
