An experiment involves picking a card from the number cards
in a standard deck of playing cards. The card is then replaced and the deck is shuffled before picking again. This process is repeated a total of 20 times to gather data on the frequency of each number card being selected.
The hypothesis for this experiment is that all number cards will be selected with roughly equal frequency, as the deck is well-shuffled and each card has an equal chance of being picked.
After conducting the experiment and analyzing the data, it is found that the number cards were indeed selected with similar frequencies, with only minor variations. This supports the hypothesis that the selection of number cards from a well-shuffled deck is random and each card has an equal probability of being picked.
