Materials: event cards, overhead spinner, spinner mat (14), regular sixsided die, 4 beans, paper cup,
coin, paper bag (containing 5 blue, 3 red and 2 yellow tiles), deck of cards (A to 10 in one suit).
 Draw 3 event cards.
 Conduct an experiment for each card. Save the data.
 Compare your theoretical probability with your experimental probability.
 Sort the cards from those where the theoretical probability and experimental probability were most similiar, to those where they were the most different.
Questions:
 Is it common for the experimental probability and theoretical probability to be exactly the same? Why?
 List some reasons which might explain the differences between theoretical probabilities and the experimental probabilities you obtained.
