This activity shows the classic marble example of elementary probability.
Probability marbles in a bag simulator.
The sample space for the second event is then 19 marbles instead of 20 marbles.
Learn about sampling with and without replacement by randomly drawing marbles from a bag.
On a mission to transform learning through computational thinking shodor is dedicated to the reform and improvement of mathematics and science education through student.
The results are shown in the tables below.
If i ever write a different non frames version i ll put a link to it here.
This is called probability without replacement or dependent probability.
The probability of picking a yellow marble.
Number of object distinct from the others m.
Once you have decided on your answers click the answers checkboxes to see if you are right.
Change the number of marbles of different colors in the boxes and guess the probability of drawing a red blue or yellow marble.

This math education video demonstrates how to calculate the probability of removing colored marbles from a bag.
Number of objects picked n.
For example a marble may be taken from a bag with 20 marbles and then a second marble is taken without replacing the first marble.
Sadly i had to use frames to do everything that i wanted with this page.
This was desgined to simulate a specific problem posed on the forum here.
