A stack of four cards contains two red cards and two black cards. I select two cards, one at a time, and do NOT replace the first card selected before selecting the second card. Let A be the event that the first card selected is red, and B be the event that the second card selected is red. The events A and B are: independent. complements. dependent. disjoint.

00:01 Hi, i'm david and i'm here to help you answer your question.

00:03 Now let me bring up your question here.

00:06 In this question here, we will discuss about the concept of the independent complement and dependent and the charm.

00:15 Now let me use the venn diagram to describe it to you.

00:21 Suppose i give you the case that we have, this will be the one, two, and three, and then then this one will be the event a, the second will be the event b, it will be event c.

00:40 So we see that they are the distraught because they have no overlaps.

00:46 So a, b, c are disowned because there is no overlap between them.

01:06 And then we will call the common if we consider the a and b plus c together.

01:16 So if we consider the not in a but and then the whole thing here will be the b plus c that will take up on the entire space and if we consider like this and then they are complement.

01:32 And then for the dependent and independent, it will be the concept of the probability.

01:44 So independent means that a b, if the probability of the a and b happen at the same time, it will equal to the probability a times probability b.

02:05 And if not then they are dependent.

02:08 Now in this question here we have a stack of four cards from 10 two red and two blacks so we have the set of the four card here and then we will have the two red and then two blacks and then we're going to select two cards without replacement one at the time and the event a it will be the first card is red, the event b, it will be the second cut is red...
