Jolene rolled a six sided dice 400 times. She rolled 100 ones. Jolene said this dice was probably not a fair dice. Why did she say this?
The theoretical probability of landing a one on a fair dice is 1/6 , but she rolled a one 1/4 of the time. After 400 rolls, the experimental probability should be closer to the theoretical probability.
