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 taking the frequency of R divided by the total number of outcomes:
P(R) = Frequency of R / Total number of outcomes
P(R) = 30 / 100
P(R) = 0.3
To convert this to a percentage, we multiply by 100:
P(R) = 0.3 * 100
P(R) = 30%
Therefore, the probability of picking the letter R is 30%.
