What is the probability that both marbles will be the same color?

You can cross check with what I presented here and you will find they are the same. Which gives a probability of about 38\%.

What is the probability that two marbles are red?

If the marble is not “replaced”, the probability of the second drawing changes, since there are less marbles in the jar. The probability of drawing a red marble = 2/5.

What’s the probability of picking a red marble?

The probability of drawing a red marble = 2/5. The probability of drawing a blue marble is now = 1/4. The probability of drawing a red marble = 2/5.

What is the probability of selecting a red marble?

Correct answer: Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375.

How many marbles are in a bag of marbles?

A bag contains 3 red marbles, 2 blue marbles, and 5 green marbles. What is the probability of randomly selecting a blue marble, then without replacing it, randomly selecting a green marble? | Socratic A bag contains 3 red marbles, 2 blue marbles, and 5 green marbles.

What is the probability that 2 randomly chosen marbles are not pink?

To obtain the probability that is asked, simply compute 1 – (2/9) = 7/9. The probability that the 2 randomly chosen marbles are not both pink is 7/9.

What are the odds of finding the green marble?

Selecting the first green marble has a 6/20 chance, the second green marble has a 5/19 chance. This gives a total chance of 30/380, or a 3/38 chance. There is a special contest held at a high school where the winner will receive a prize of $100. 300 seniors, 200 juniors, 200 sophomores, and 100 freshmen enter the contest.

How do you solve for the difference in marbles?

We can also solve this as an inequality. You take the difference in marbles, which is 3, which means you need the difference in green and blue marbles to be greater than 3, or at least 4. You have b + g = 13 and g – b > 3, where b and g are positive integers.
