The probability of picking a letter R can be calculated by taking the frequency of R (30) and dividing it by the total number of picks (100):
Probability = Frequency of R / Total number of picks
Probability = 30 / 100 = 0.30
To express this probability in percent form, we multiply by 100:
Probability = 0.30 * 100 = 30%
Therefore, the probability that Jorelle will pick a letter R is 30%.
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.
