A jar contained 6 red marbles, 10 green marbles, and 8 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 50 trials. What was the relative frequency of selecting a red marble? Round to the nearest percent, if necessary.

Ok relative frequency is basically the amount of times that you selected a red marble divided by the total amount of trials
How many times did you select a red marble? out of the 50 trials Thats just another way of looking at it
relative frequency is basically the outcomes that occurred but in percentage format
Relative frequency of selecting red =\(\frac{\text{amt of times selected red}}{\text{ total amt of trials}}\)
Frequency of a particular outcome/total number of experiements.
So total up 10 + 24 + 16 = ?
50
Ok And there are 10 Reds. Now divide :D 10/50 = ?
0.2
20?
is 20 the answer?
Yep!

No problem! :)
