What is the probability of drawing a red marble replacing it and then drawing another red marble. Two marbles are drawn at random without replacement.

I have a drawer with 10 socks in it. Identify the following compound event as independent or dependent and then find the probability of the events both occurring. We are not replacing it. Or in particular the second pick is dependent on the first.

The events are dependent. Let me make this clear not independent. P green then red p green p red given green occurred 3 5 2 4 6 20 3 10. There is a 2 5 chance of pulling out a blue marble and a 3 5 chance for red.

I randomly select a sock from the set of blue socks and then i randomly select a sock from the set of red socks. Preview this quiz on quizizz. This is called probability without replacement or dependent probability. A box contains 2 red marble 3 white marble 4 green marbles and 1 blue marble.

The sample space for the second event is then 19 marbles instead of 20 marbles. A bag contains 6 marbles 3 red and 3 blue.
