Example: When people play bridge, they randomly determine one of the washed playing cards as the starting card. At this time, when moving cards in sequence, for any family, draw 13 cards from 52 cards. Is this sampling method a simple random sampling? [Analysis] The essence of simple random sampling is to randomly select samples from the population one by one, where only the starting cards are randomly determined. Although all the other cards are played one by one, whose hand has been determined, so it is not a simple random sampling.
