1.

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.

Answer»

-step explanation:What is the best explanation of how do you find the EXPERIMENTAL probability of rolling a 3 to find the experimental probability of rolling a three WRITE a ratio of the NUMBER of times three occurs to the total number of trials SIMPLIFY if necessary to find the experimental probability of rolling a three write a ratio of the total?
