The local grocery store wants to know if the shoppers prefer Crest or Colgate

toothpaste. The store gives all of its shoppers a value saver card, then uses a random
number generator to select 500 card numbers and surveys those shoppers.
Is this sampling method representative of the entire population and explain?

Answer:Yes it is because it uses probability. If there are 500 cards a and 500 people, then there is a 50/100 chance that it will be Crest or Colgate.
