Given:

A jar contains 30 red marbles, 50 blue marbles, and 20 white marbles.

So, the total number of marbles =


30+50+20=100

We will find the theoretical probability of choosing a red marble

The number of red marbles = 30

So, the percentage probability will be as follows:


(30)/(100)*100=30\%

So, the answer will be:

The theoretical probability = 30%
