A coin is tossed and then the spinner is spun. Determine the probability that you toss Heads and spin a Red.

• 1/6

• 1/10

• 0

• 1/12

Is the following compound event independent or dependent
P(1 and A)

• Independent

• Dependent

Inger keeps her white and black chess pieces in separate bags. For each color, there are 8 pawns, 2 rooks, 2 bishops, 2 knights, 1 queen, and 1 king. Are the events of drawing a knight from the bag of white pieces and drawing a pawn from the bag of black pieces dependent or independent events? Find the probability of this compound event.

• Independent; drawing a piece from one bag does not affect the pieces in the other bag; 1/16

• Dependent, drawing a piece from a bag affects the pieces in the other bag; 1/16

• Independent; drawing a piece from one bag does not affect the pieces in the other bag; 1/4

• Dependent, drawing a piece from a bag affects the pieces in the other bag; 1/4
