What is the theoretical probability of rolling a 3 on a fair six-sided die?

In an experiment, a coin is flipped 100 times and lands on heads 55 times. What is the experimental probability of getting heads?

• 0.45

• 0.50

• 0.55

• 0.60

• The experimental probability is higher than the theoretical probability.

• The experimental probability is lower than the theoretical probability.

• The experimental probability is equal to the theoretical probability.

• The experimental probability cannot be determined.

Which type of graph would best represent the distribution of students' test scores in a class?

• Line plot

• Circle graph

• Histogram

• Stem-and-leaf plot

What can be concluded from a histogram that shows a large peak in the middle of the data range?

• The data is skewed to the right.

• The data is skewed to the left.

• The data is normally distributed.

• The data has no pattern.

If a die is rolled 60 times and the number 4 appears 10 times, what is the experimental probability of rolling a 4?

A bag contains 5 red marbles, 3 blue marbles, and 2 green marbles. What is the theoretical probability of drawing a blue marble?

How does increasing the number of trials in an experiment affect the experimental probability?

• It makes the experimental probability closer to the theoretical probability.

• It makes the experimental probability less accurate.

• It has no effect on the experimental probability.

• It makes the experimental probability more random.

Which graphical representation is best for showing the proportion of different categories in a data set?

• Histogram

• Line plot

• Circle graph

• Stem-and-leaf plot

What pattern might a histogram reveal that is not easily seen in a data table?

• The exact values of the data points

• The mean of the data set

• The mode of the data set

• The distribution shape of the data
