1: Nikita performed an experiment in which she randomly pulled a marble from a bag, recorded its color, placed it back in the bag, and then repeated. The results are shown in the following table.
Result Frequency
Red 20
Purple 24
Blue 12
Based on the experiment, what is the probability of drawing a blue marble?
Enter your answer as a fraction, like this: 42/53
total draws: 20+24+12 = 56
so, P(blue) = 12/56
