, 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.

Answer 1

To find the probability that Jorelle will pick a letter R, we can use the formula:

\[ P(R) = \frac{\text{Frequency of R}}{\text{Total number of trials}} \]

From the given data, the frequency of R is 30, and the total number of trials is 100.

Now we can calculate the probability:

\[ P(R) = \frac{30}{100} = 0.30 \]

To express this probability in percent form, we multiply by 100:

\[ P(R) = 0.30 \times 100 = 30% \]

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