Y8 Final Jeopardy

Set Notation

100

Pronounce: P(A|B)

probability of A given B

200

Pronounce: P(A ∩ B) and give the formula if A and B are independent.

Probability of A intersect B

P(A) * P(B)

300

Pronounce P(A U B)

Give the formula if A and B are independent.

Probability of A union B

P(A) + P(B) - P(A)*P(B)

400

Give an example that demonstrates intersect probability of two independent events using a deck of cards.

  

500

Give an example that demonstrates union probability of two independent events using a deck of cards.

Quadratics

100

Solve: x² - 6x + 8 = 0

x = 2, 4

200

Solve: 2x² - 7x + 3 = 0

x = 1/2, 3

300

Complete the Square (write in vertex form):

x² - 7x + 3 = 0

(x - 7/2)² - 37/4

400

Complete the square: 

4x² - 7x + 6 = 0

4(x - 7/8)² + 47/16

500

Solve: 2x² - 5x +12 = 0

x = 5/4 +/- i(sqrt(71) / 4)
