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.
(1 point)
The probability of picking a letter R is the frequency of picking R divided by the total number of outcomes.
Frequency of picking R = 30
Total number of outcomes = 100
Probability of picking R = 30/100 = 0.3
Convert probability to percentage:
0.3 x 100% = 30%
Therefore, the probability that Jorelle will pick a letter R is 30%.
