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. A bag has 3 red marbles 2 blue and 4 yellow.

So they say the probability i ll just say p for probability. Find the probability of pulling a yellow marble from a bag with 3 yellow 2 red 2 green and 1 blue i m assuming marbles. But after taking one out the chances change. Total number of objects n.

Number of objects picked among those distinct k. Total number of outcomes. What are the chances of getting a blue marble. Number of objects picked n.

Number of ways it can happen. 5 there are 5 marbles in total. The sample space for the second event is then 19 marbles instead of 20 marbles. Number of object distinct from the others m.

If we got a red marble before then the chance of a blue marble next is 2 in 4. What is the probability that a blue marble gets picked. And so this is sometimes the event in question right over here is picking the yellow marble. Marbles in a bag.

So the probability 4 5 0 8. 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 probability of picking a yellow marble.
