The table shown summarizes 100 items by type and category. One type item will be selected at random. What is the probability that the selected item will be in category 3 ?

Based on the graph above, in how many of the games played did the soccer team score goals equal to the median number of goals for the 29 games?

The sum of all values across the observations divided by the overall sample size is the mean of the set of observations.
The value of the specified number of observations that divides it into two parts is its median. Therefore, based on the proportion of even or odd observations, it is possible to calculate the median of ungrouped data when the data are arranged in descending or ascending order.
The observational value with the highest frequency is the mode.
Data mean sum of all observations divided by the total number of observations.

Based on the graph above, in how many of the games played did the soccer team score goals equal to the median number of goals for the 29 games?
