Probability with Cards
Obtain a standard deck of 52 cards, and mix them well. You are going to perform
an experiment to estimate the probability of drawing a club, a diamond, a heart,
and a spade from your 52 cards.
Directions:
1. Shuffle the cards well. Draw one card. Record in the appropriate box below.
2. Replace the card and shuffle.
3. Draw another card and record its suit.
4. Repeat the above steps until you have recorded a total of 25 draws.

How do your experimental probabilities compare with the theoretical

How do the class experimental results compare to the theoretical probabilities?
Suppose we recorded 2,500 draws in our experiment. How do you think the
experimental probabilities will compare to the theoretical probabilities then?
What statistical law is exhibited here?
