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: 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

r u sure

Answer 2

The probability of picking a letter R can be calculated by dividing the frequency of picking R by the total number of trials:

Frequency of picking R = 30
Total number of trials = 100

Probability = Frequency of picking R / Total number of trials
Probability = 30 / 100
Probability = 0.3

To convert the probability to a percentage, we multiply by 100:

Probability = 0.3 x 100
Probability = 30%

Therefore, the probability that Jorelle will pick the letter R is 30%.

Answer 3

Let's recalculate by adding the frequency of picking the letter R and dividing by the total number of trials:

Frequency of picking R = 30
Total number of trials = 100

Probability = Frequency of picking R / Total number of trials
Probability = 30 / 100
Probability = 0.3

To convert the probability to a percentage, we multiply by 100:

Probability = 0.3 x 100
Probability = 30%

Therefore, the probability that Jorelle will pick the letter R is 30%.
