Probability Of Picking Marbles In Order

Suppose we number the marbles 1 to 10.

Probability of picking marbles in order. Since the first green marble is not returned the probability of picking another green marble 3 19. What is the probability of picking out number 5. P getting a color other than red p 25 55 455. Well there is only one number 5 marble and there are still 10 marbles in the jar so the answer is 1 marble favorable outcome divided by 10 marbles size of sample space 1 10 or 10 percent.

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. If we got a blue marble before then the chance of a blue marble next is 1 in 4. A jar contains 30 red marbles 12 yellow marbles 8 green marbles and 5 blue marbles. If we got a red marble before then the chance of a blue marble next is 2 in 4.

What is the probability that you draw and replace marbles 3 times and you get no red marbles. Probability of this happening 3 times in a row is found by 455 455 455 094. This is because we are removing marbles from the bag. 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.

So they say the probability i ll just say p for probability. The sample space for the second event is then 19 marbles instead of 20 marbles. And so this is sometimes the event in question right over here is picking the yellow marble. This is called probability without replacement or dependent probability.

The probability of picking a yellow marble.
