First, find the sum of all the marbles that you have. That is 100 in total.

The probability of you getting a blue marble is 50/100, or 1/2, or 50%

A red marble is 30/100, or 3/10, or 30%

White 20/100, 1/5, 20%

Probability is the likelihood or chance that an event will occur. The theoretical probability for the red, blue and white are 0.3, 0.5 and 0.2

What is probability?

Probability is the likelihood or chance that an event will occur. Mathematically;

Probability = expected outcome/Total outcome

Find the total outcome

Since the jar contains 30 red marbles, 50 blue marbles, and 20 white marbles, the total outcome is 100marbles

Calculate the theoretical probabilities

For the red marbles

Pr(selecting red marbles) = 30/100 = 0.3

For the blue marbles

Pr(selecting blue marbles) = 50/100 = 0.5

For the white marbles

Pr(selecting white marbles) = 20/100 = 0.2

Hence the theoretical probability for the red, blue and white are 0.3, 0.5 and 0.2
