If one event can occur in m ways and another event can occur in n ways, then the number of ways the two event happen in sequence is given by

• m + n

• mn

• m - n

• mⁿ

If the occurrence of one event does not affect the occurrence of another event, the two events are

• dependent

• conditional

• indentical

• independent

Which events are dependent?

• selecting a king from a standard 52 card deck and then a queen without replacing the king

• Flipping a coin and rolling a 4-sided die

• Having two children both with blue eyes

• Making 2 three-pointers in a row during a basketball game

In a sequence of independent events, the probability that at least one event is successful is equal to

• 1

• 1 - P(all)

• P(none) - 1

• 1 - P(none)
