\[\frac{2}{5}\]
\[\frac{3}{10}\]
\[\frac{1}{2}\]
If the probability of event A happening is \(\frac{6}{13}\), what is the probability of it not happening?

\[\frac{6}{13}\]
\[\frac{7}{13}\]
James counts the number of yellow cars passing his window. Out of a total of 50 cars counted, 15 were yellow. What is the relative frequency of yellow cars?
\[\frac{35}{50}\]
\[{24}\%\]
James says that the probability that the next car to pass his window will be yellow is \(\frac{15}{50}\). What is the problem with James’s statement?
Relative frequency and probability are not related
The correct probability is \(\frac{16}{51}\)
\(\frac{15}{50}\) is only an approximation to the true probability
