A spinner is divided into nine equal sections numbered 1 through 9. Predict how many times out of 270 spins the spinner is most
likely to stop on an odd number. Question 1 options: 70 150 200 240 Rowan has a bag containing 20 marbles. The table below shows the number of marbles of each color in the bag. As part of a probability experiment for his math class, Rowan randomly picks a marble from the bag and then replaces it. He repeats this 200 times. Predict the number of times out of 200 Rowan will pick a blue marble.

What is the probability that a number less than 2 will occur on one toss of the number cube? Question 5 options: 1/6 2/6 3/6 4/6 Save Question 6 (3 points) Question 6 Unsaved A set of five quadrilaterals consists of a square, a rhombus, a rectangle, a trapezoid, and a parallelogram. Sally selects one of these figures at random. What is the probability that only one pair of the figure’s opposite sides are parallel? Question 6 options: 1/5 3/5 4/5 2/5 Save Question 7 (3 points) Question 7 Saved Maelee’s Book Store has received a shipment of books. The table below shows the number of each type of book in the shipment. Maelee selects a book at random from the shipment. What is the probability that she chooses a children’s picture book?

Question 8 options: rolling an odd number rolling an even number rolling a number less than 4 rolling a number greater than 1 Save Question 9 (3 points) Question 9 Unsaved The spinner below is divided into twelve equal regions and is spun once. What is the probability of not getting red? Question 9 options: 1/12 6/12 7/12 5/12 Save Question 10 (3 points) Question 10 Unsaved Based on Robert’s baseball statistics, the probability that he will get a hit is 3/4.
