200

The probability of rolling a die and getting an even number.

What is 1/2 , 0.5, or 50%?

200

This type of sample is chosen randomly, giving each member of the population an equal chance of being selected.

What is a random sample?

500

This term refers to the extent to which sample statistics differ from the corresponding population parameters due to chance.
