general conjunction rule used to compute the probability of two events occuring together whether or not the events are independent
restricted disjunction rule used to compute the probability of either of two events occuring when the events are mutually exclusive

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
