I’m going to start off with my regular pack of 52 cards because a lot of probability questions will relate to cards. So you must know very very well on what in a pack of cards what they consist of. You can see over here I’ve got all these pictures of all the parts in the cards and you have to know how many of each and what different colors there are as well. So you can see we have four aces and we don’t have the number one. So make sure you don’t think that there’s a one in the cards. It always starts from two up to ten and it’s always four of each card. So you can treat a being the number one and we have court cards.
Court cards are jack, queen, and king. So we have four of each as well. When we’re looking at probability, we don’t consider any jokers. So don’t think that there’s any jokers in the cards. They’re always neglecting jokers, so don’t worry about jokers and any probability questions, okay? Unless they do specify but it’s really rare for them to specify for any jokers. So this is all you need to consider. And you should also know that there are black cards and red cards. If you count them up, you can see that there’s 52 cards in total. So you must remember that number 52.
With these card questions I do recommend for you to draw up this table at the beginning of the question and then just relate to these cards, relate to this table whenever you answer a question because once you draw this table, answering the question is really really simple. It’s just no matter of counting up some blocks. I’ve got diamond, heart, clover, and a spade here. You can see that so there’s four shapes in the card pack of cards and I’ve got up to ten, jack, queen, and king. It says picture cards and you can see this part here colored in blue.
In this part, these three are simply the picture cards. One, two, three, four! One, two, three, so 12 in total. Red cards are just these two. These two are red cards. pretty much just half of the cards. A half a red, half of black. So red cards are just exactly half. Black cards are these two so again, similar to the red card! It’s half of the pack of cards, half the cards are black.
