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%.
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.
