Question

Da letter tiles C, A, R, E, and S r placed in a box. Without looking, Jorelle picks a letter tile from da box n records da result b4 placing it back. He repeats da procedure 100 times n observes da following results:

Da table represents da frequency of oxxurrences 4 letters C,A,R,E, and S when Jorelle picks them from da box

Outcomes C A R E S
Frequency 20 25 30 10 15

Based on da observed frequency, wut is da probability dat Jorelle will pcika letter R? Da answer should b in percent from


_____%

Answer 1

To calculate the probability that Jorelle will pick the letter R based on the observed frequency, you can use the formula for probability:

\[
\text{Probability (P)} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}
\]

From the data provided:

- Frequency of R = 30
- Total frequency (number of trials) = 20 + 25 + 30 + 10 + 15 = 100

Now, substituting these values into the probability formula:

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

To convert this probability into a percentage, multiply by 100:

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

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