Question

A jar contains 30 red marbles, 50 blue marbles, and 20 white marbles. You choose one marble from the jar at random. What is the theoretical probability of choosing a red marble?20%50%80%30%

Answer 1

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:

$\frac{30}{100}\times100=30\%$

So, the answer will be:

The theoretical probability = 30%
