Calculate the mean of this dataset

What is the probability of selecting a square from the shapes below?

The theoretical probability for a special outcome is . Someone does an experiment about this event with 30 trials.

Out of the 30 trials, how many times should we expect to get the special outcome? In other words, for the 30 trials, what is the most likely number of times we will get the special outcome?

A learner finds a novel (400 pages) and then selects one page from the textbook. What is the probability that the page has an odd page number?

A group of students conducted an experiment by rolling a fair six-sided die 100 times and recorded the outcomes. They observed that the number 3 appeared 20 times. Which concept would be most appropriate to use to analyze this experiment?

A die is tossed 28 times and lands 6 times on the number 6.

What is the relative frequency of observing the die land on the number 6?

A learner finds a novel (300 pages) and then selects one page from the textbook. What is the probability that the page has an even page number?

The following is a list of data:

Determine the value of if the set has the following box-and-whiskers plot

If a fair six-sided die is rolled, the probability of it landing on an even number is 

The above scenario is an example of theoretical probability. 

Percentile is a value which tells us how far along through an ordered data set a certain value sits. Percentile is related to minimum and maximum values in a data set and to the quartiles.

Which of the following is the value which corresponds to the 0th percentile?
