The letter tiles C, A, R, E, 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 results, we can calculate the experimental probability of each outcome by dividing the frequency of each letter by the total number of trials (100).

Experimental probability of drawing:
- The letter C = Frequency of C / Total number of trials = 20/100 = 0.2 = 20%
- The letter A = Frequency of A / Total number of trials = 25/100 = 0.25 = 25%
- The letter R = Frequency of R / Total number of trials = 30/100 = 0.3 = 30%
- The letter E = Frequency of E / Total number of trials = 10/100 = 0.1 = 10%
- The letter S = Frequency of S / Total number of trials = 15/100 = 0.15 = 15%
