Given table:
color ----- Frequency
Red ------ 14
Green ----- 19
Blue -------- 21
Yellow ----- 16
Number of process repeated (trials) = 70 times
Probability (event) = number of times the event occurs / total number of trials
From the table we can see that the number of times she pick the blue marble is 21
Probability of picking a blue marble on next try = =
