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?

Answer 1

The total number of marbles is 30+20+50= 100, so. Since there are 20 red marbles and 50 blue marbles. There are 30+50=80. 80/100=4/5= 80%

Answer 2

Answer:

30%

Step-by-step explanation:

30+50+20=100, and since there's 30 red marbles, you have a 30% chance of picking a red out of the 100 marbles.
