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 a letter R can be calculated by dividing the frequency of R by the total number of trials:
P(R) = frequency of R / total number of trials
P(R) = 30 / 100
P(R) = 0.3
To convert to percent form, we can multiply by 100:
P(R) = 0.3 x 100
P(R) = 30%
Therefore, the probability that Jorelle will pick a letter R is 30%.
To find the probability of picking a letter R, we need to divide the frequency of picking the letter R (30) by the total number of trials (100):
Probability = Frequency of R / Total number of trials
Probability = 30 / 100 = 0.3
To convert the probability to a percent, we multiply by 100:
Probability in percent = 0.3 * 100 = 30%
Therefore, the probability that Jorelle will pick a letter R is 30%.
To find the probability of picking the letter "R" from the box, we need to divide the frequency of "R" by the total number of trials (which in this case is 100).
From the given data, we can see that the frequency of "R" is 30.
So, the probability of picking the letter "R" is:
Probability = Frequency of R / Total trials = 30 / 100 = 0.3
To convert this probability into percent form, we can multiply it by 100:
Probability in percent = Probability * 100 = 0.3 * 100 = 30%
Therefore, the probability of Jorelle picking the letter "R" is 30%.
