Assume a good deck is 25% of each suit. Deal 4 cards. Record the number of cards for each suit. Calculate the proportion or percentage of each suit. (You can just focus on one suit if you want, e.g., hearts; 1 heart out of 4 would be .25 or 25% hearts.) Did you get 25% cards of each suit? Why or why not? Basing your decision only on the sample (pretending you do not know what is in the deck),...
