Ajar contained 12 red marbles, 16 green marbles, and 10 blue marbles. a marble was selected at random, the color was recorded, and the marble was placed back in the jar. the table shows the results after 80 trials.

what was the relative frequency of selecting a green marble? round to the nearest percent, if necessary.

outcome red green blue
number of trials 28 30 22

%

The relative frequency of selecting a green marble is 37.5%.

Step-by-step explanation:

The table after total 80 trials is given by,

Outcome                    Number of trials

Red                                      28

Green                                  30

Blue                                     22

Since, 'Relative frequency' is the ratio of the number of times an event is occurring to the total number of events.

Thus, we have,

Relative frequency of selecting a green marble = = =0.375 or 37.5%
