1. What does the probability of the union of two events represent in terms of individual and overlapping probabilities?
2. What is the primary role of complementary events in basic probability calculations involving colored balls?
3. How should you calculate the probability of getting exactly one head when flipping two coins?
Union — definition?
Probability of either event occurring.
Complementary events — sum?
Equal to 1.
Doubles on dice — probability?
Number of doubles divided by 36.
Drawing without replacement — effect?
Changes sample space for subsequent draws.
Union in surveys — role?
Calculates probability of liking at least one option.
Color ball probability — complement?
1 minus probability of selecting that color.
