Unions and Intersections of Events Quick Check A number cube is rolled once. In Event \( A \), the number rolled is odd and in Event \( B \), the number rolled is a multiple of 3 . What is the probability of \( A \cup B \) ? (1 point) \( P(A \cup B)=\frac{1}{3} \) \( P(A \cup B)=\frac{1}{6} \) \( P(A \cup B)=\frac{2}{3} \) \( P(A \cup B)=\frac{5}{6} \)

A coin is tossed two times. In Event \( A \), each toss is different. What is the probability of the complement of Event \( A \) ? \( O P\left(A^{C}\right)=\frac{3}{4} \) \( P\left(A^{C}\right)=\frac{1}{4} \) \( P\left(A^{C}\right)=\frac{1}{2} \) \( P\left(A^{C}\right)=0 \) \( N \) Graphing Calculator

allo has a bag containing 80 marbles that are either green, yellow or red in colour. \( \frac{3}{5} \) of the rbles are green and \( 10 \% \) of the marbles are yellow. Paballo picks TWO marbles out of the bag, at a time and without replacing the first one. 1 How many red marbles are in the bag? 2 Draw a tree diagram to represent the above situation. 3 What is the probability that Paballo will choose a GREEN and a YELLOW marble?
