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 next customer ordering a white bib would be the same as any color, so the probability should be about 25%.

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.
