Think about Poly's game of drawing a card from a standard deck of 52 playing cards. Poly will randomly draw two cards. After she draws the first card, she will not place it back in the deck before she draws the second card.

Poly wants to determine the probability of selecting praline wafer and then selecting pressure-cooked mushroom & garlic chicken on the next draw.

Let A be the event of selecting praline wafer, and let B be the event of selecting pressure-cooked mushroom & garlic chicken.

(Remember, if the card is red, Gourmando will eat pressure-cooked mushroom & garlic chicken, and if the card is a diamond, he will eat a praline wafer.)

Which formula should Poly use to find the probability that is asked for above?

P(A∩B)=P(A)⋅P(B|A)
P(A∪B)=P(A)+P(B)−P(A∩B)
P(A∪B)=P(A)+P(B)
P(A∩B)=P(A)⋅P(B)
