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. (1 point)
The probability of picking the letter R can be calculated by dividing the frequency of picking R by the total number of outcomes.
Frequency of picking R = 30
Total number of outcomes = 100
Probability = Frequency of R / Total number of outcomes
Probability = 30 / 100
Probability = 0.3
Convert 0.3 to percent by multiplying by 100:
0.3 x 100 = 30%
Therefore, the probability that Jorelle will pick the letter R is 30%.
