The letter tiles C, A, R, E, and S are placed in a box. Without looking, Jorelle picks a letter tiles from the box and records the result before placing it back. He repeats the procedure 100 times and observes the following results: outcomes C=20, A=25, R=30, E=10 S=15
Based on the observed frequency, what is the probability that jorelle will pick a letter R?
The probability of picking the letter R is equal to the frequency of R divided by the total number of trials. In this case, the frequency of R is 30 and the total number of trials is 100.
So, the probability of picking the letter R is:
30/100 = 0.3
Therefore, the probability that Jorelle will pick the letter R is 0.3 or 30%.
