2. A jar contains blue, red, yellow, and green marbles. P(blue)=1/4. What type of probability is illustrated and why?
A. Experimental; the result is based on the number of possible outcomes.
B. Experimental; the result is found by repeating an experiment.
C. Theoretical; the result is based on the number of outcomes.
D. Theoretical; the result is found by repeating an experiment.***?
Repeating an experiment naturally gives rise to experimental probability.
Since no experiment is described, the probability must be theoretical only. So, (C).
Steve is correct.
thank you for correcting me!
Mandy Usane is wrong!!!!!! I got a 6/18 33.3%
Is dnf right?

The type of probability illustrated in this scenario is theoretical probability, which is why the correct answer is option D.
Theoretical probability is based on mathematical calculations using the number of possible outcomes. In this case, the probability of drawing a blue marble is given as 1/4. This implies that out of all the marbles in the jar, one-fourth of them are blue. The probability is not determined through repeated experiments but rather through understanding the composition of the jar.
Experimental probability, on the other hand, involves conducting repeated experiments and calculating the probability based on observed results. For example, if you were to randomly draw marbles from the jar several times and record the number of blue marbles obtained, you could calculate the experimental probability of drawing a blue marble based on the frequency of occurrence.
In summary, since the given probability is based on the composition of the jar rather than the result of repeated experiments, it falls under the category of theoretical probability.
are they right
these are the answer i think :)
1. experimental; the result is found by repeating an experiment
2. theoretical; the result is based on the number of possible outcomes
