The union and intersection of events (essentially "or" and "and"conditions in word problems) is an important distinction that can result in greater success if learned or more confusion if not considered formally. … �]����:�E6�a��3OӾ�ڦّ�!��[s�0r�a�2]��e��MT

In this problem, the probability of drawing a red ball is 0.1 if either of the two buckets is selected, which explains the independence between the events. Many problems in this section guide students to practice both. i���KRv&��q4Y��T��s7 ��

This new version of our puzzles does NOT require any Java applets. They will analyze real-life word problems to calculate both experimental and theoretical probability. In the case when the events A and B are independent the probability of the intersection is the product of probabilities: P(A¢B) = P(A)P(B): Example: The outcomes of two consecutive ﬂips of a fair coin are independent events. fair, all outcomes are equally likely.
