Probability Assessment

A container consists 2 red flags, 3 blue flags, and 3 yellow flags. If Seth chooses a flag to keep, what is the theoretical probability of choosing a purple flag?

• 0%, Impossible 
• 15%, Not likely 
• 88%, Likely 
• 100%, Certain

A bag has 3 red marbles, 2 blue and 4 yellow. What is the theoretical probability of pulling a red?

• Likely at 76.7%
• Unlikely at 13.8%
• Impossible at 33.3%
• Unlikely at 33.3%

Which probability is being described?
"Thinking" about the number of desired outcomes over the total number of outcomes for an event. 

• Theoretical Probability 
• Experimental Probability 

Which probability is being described? 
The ratio of the actual times an event occurs in an experiment over the total number of times the experiment was done.

What is the probability of NOT spinning green or yellow on this spinner?

• 66.7%
• 33.3%
• 12.5%
• 55%

Is this a fair spinner? Explain. 

• Yes, red occurs more frequently. 
• No, yellow occurs less frequently and red more frequently. 
• Yes, all four colors are equally represented.
• No, blue and green are equal amounts. 

Deion has two bags of marbles. In the bag labeled ‘A’, he has 3 green, 4 blue and 10 yellow marbles. In the bag labeled ‘B’, he has 13 green, 5 blue, and 12 yellow marbles. Deion wants the bag with the highest probability of selecting a yellow marble. Which of the following statements is true?

• It does not matter which bag he chooses because the probabilities are the same.
• He should choose Bag B because there are fewer blue marbles.
• He should choose Bag A because the probability of selecting a yellow marble is higher.
• He should choose Bag B because the probability of selecting a yellow marble is higher.

Using the table given, find the experimental probability of spinning
Letter T.

• 100%
• 30%
• 48%
• 70%

The six faces of a fair number cube are numbered 1 through 6.  What is the theoretical probability of landing on a number greater than or equal to 5? 

• 16.7%
• 33.3%
• 66.7%
• 50%

Sydney has index cards numbered 1 through 10 and determines that the experimental probability of drawing a number less than 4 is 60%. If she draws cards 400 times, how many times can she expect to draw a number less than 4? Use proportions. 

• 120
• 60
• 380
• 240
