Understanding Experimental Probability

What are the three possible outcomes when tossing a paper cup?

• Open end up, closed end up, on its side

• Open end up, on its side, floating in air

• Open end up, open end down, on its side

• Open end down, closed end down, on its corner

What is the experimental probability of the cup landing on its side in the paper cup tossing activity?

• 18 out of 20

• 20 out of 20

• 2 out of 20

• 0 out of 20

• It would increase

• It would decrease

• It would stay the same

How do you calculate the experimental probability of an event?

• Number of times the event occurs divided by the total number of trials

• Number of times the event does not occur divided by the total number of trials

• Total number of trials divided by the number of times the event occurs

• Number of trials minus the number of times the event occurs

What does a batting average of 250 mean in the baseball team simulation?

• The team misses the ball 75% of the time

• The team hits the ball 25% of the time

• The team has a 250% chance of hitting the ball

• The team hits the ball 250 times

How can you use a standard deck of cards to simulate hits in baseball?

• Use only the black cards to represent hits

• Use only the red cards to represent hits

• Let diamonds represent a hit, and all other suits represent no hit

• Let hearts represent a hit, and all other suits represent no hit

How would you use a number cube to predict which color ball Ross will get next from the toy machine?

• Assign two numbers to each color and roll the cube 50 times

• Assign one number to each color and roll the cube 30 times

• Use only even numbers to predict the color

• Roll the cube once and choose the color randomly
