Question

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:

The table presents the frequency of occurrences for letters C, A, R, E, and S when Jorelle picks them from the box.
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.

(1 point)

Answer 1

Observed frequency for R = 30 out of 100 trials, so probability = 30/100 = 0.30 = 30%.
