Tiffani works in a baby shop in which she prints personalized bibs. she uses a probability model to predict that the next customer ordering a white bib would be 30%. for one day, tiffani gathers data by tallying the the number of customers who order each color in this table.
color tally
white 21
grey 9
blue 15
pink 26
based on her experiment, which statement is true?
tiffani's prediction is valid. the probability of the next customer ordering a white bib is about 30%.
tiffani's prediction is not valid. the probability of the next customer ordering a white bib should be about 21% because 21 people ordered white in her data.
tiffani's prediction is not valid. the next customer ordering a white bib would be the same as any color, so the probability should be about 25%.
there is not enough information to determine the validity of her prediction.
