Alex has a spinner divided into 8 equal parts with the numbers 1 – 8 on each part. He spins the spinner one time. This is the probability, expressed as a percent, that he will spin a number that is a factor of 8.

What is 50%? Explanation: The numbers 1, 2, 4, and 8 are all factors of the number 8, so 4 of the 8 numbers are factors of 8 and 4 are not. So, Alex has a 50% chance of spinning a factor of 8.

The spinner to the left is divided into 5 equal parts The spinner to the left is divided into 5 equal parts. The spinner is spun 1000 times. According to theoretical probability, this is the number of times it should land on the letter A.

What is 200 times? Explanation: According to theoretical probability, the spinner should land on each section the same number of times. So, if should land on each number 200 times since 200 x 5 = 1000.

Mr. Linden wrote all the letters in his last name on 6 different pieces of paper. He then put the 6 pieces of paper in a paper bag and took 1 piece out at random. This is the probability, expressed as a lowest term fraction, that the letter he took out was the letter ‘n’.

What is 1/3? Explanation: The word LINDEN has six letters, but two of them are the letter N. 2/6 in lowest terms is 1/3.

Of the following choices, this is the number of possible outcomes in the above situation. 2 6 8 12

What is D. 12? Explanation: To find the number of possible combinations, you need to multiply the number of choices for each. The coin can land on heads or tails, so that is two choices. The cube has six different possible choices. 6 x 2 = 12.

Andy has 20 marbles in a bag Andy has 20 marbles in a bag. 10 of them are red, eight are black, and the rest are blue. Andy plans to take out a marble out of the bag, record its color, and then return the marble to the bag. He plans on doing this 10 times. According to theoretical probability, this is the number of times he should pull out a blue marble out of the 10 times.

What is 1 blue marble? Explanation: According to the information given, 2 out of the 20 marbles are blue, which is 10% of the marbles. If he is going to pull out 10 different marbles, that means that 10% of them should be blue, which is one marble.
