The letter tiles C, A, R, E, and S are placed in a box. Without looking, Jorelle picks a letter tile from the box and records the result before placing it back. He repeats the procedure 100 times and observes the following results:
Outcomes C A R E S
Frequency 20 25 30 10 15
Based on the observed frequency, what is the probability that Jorelle will pick a letter R? The answer should be in percent form.

The probability of picking a letter R can be calculated by dividing the frequency of picking a letter R by the total number of trials.
Frequency of picking R = 30
Total number of trials = 100
Probability of picking R = Frequency of picking R / Total number of trials
= 30 / 100
= 0.3
Converting it to percentage:
Probability of picking R = 0.3 * 100%
= 30%
Therefore, the probability that Jorelle will pick a letter R is 30%.
