Replacing A Marble Independent Or Dependent

I have a drawer with 10 socks in it.

Replacing a marble independent or dependent.

Find the probability of problems work space selecting a green marble in a second draw if the first marble is blue. This is called probability without replacement or dependent probability. 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. Remember we take the marble out.

P green then red p green p red given green occurred 3 5 2 4 6 20 3 10. Let me make this clear not independent. Preview this quiz on quizizz. The events are dependent.

So these are not independent events. Two marbles are drawn at random without replacement. Or in particular the second pick is dependent on the first. A box contains 2 red marble 3 white marble 4 green marbles and 1 blue marble.

A bag contains 6 marbles 3 red and 3 blue. Because the first marble is replaced the size of the sample space 9 does not change from the first drawing to the second so the events are independent. Six are blue and four are red. Independent 1 2 dependent 1 2 dependent 1 4 independent 1 4.

We are not replacing it. By not replacing the marble after the first draw the probability of the second draw is affected. Answer since i m not drawing with replacement it s tempting to think that these are dependent events but they. Are the two events dependent or independent.

First a red colored marble is drawn and then without replacing the first marble a blue colored marble is drawn. Is a wonderful way to picture what is going on so let s build one for our marbles example. The sample space of the second draw has changed leaving only 4 marbles. 5th 8th grade.

One marble is removed from the box and then replaced. So there s not any replacement here. Draws are made without replacement. I randomly select a sock from the set of blue socks and then i randomly select a sock from the set of red socks.

Identify the following compound event as independent or dependent and then find the probability of the events both occurring. Dependent events are what we look at here. What is the probability that the first marble is blue and the second marble is green. Another marble is drawn from the box.

The sample space for the second event is then 19 marbles instead of 20 marbles. Are these independent events or dependent events. What is the probability of drawing a red marble replacing it and then drawing another red marble. We can go one step further and see what happens when we pick a second marble.

Are the two events dependent or independent. A box contains 5 purple marbles 3 green marbles and 2 orange marbles.
