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 the letter R is the frequency of R divided by the total number of trials:
Probability = Frequency of R / Total Trials = 30/100 = 0.3
Converting this probability to a percentage, we get:
Probability = 0.3 x 100% = 30%
Therefore, the probability that Jorelle will pick the letter R is 30%.
