Alright, for this question, a card is selected at random from a standard deck of cards.
00:06
So in a standard deck of cards, there are 52 total cards.
00:10
There are 13 cards in each suit.
00:13
So we'll say this is the total.
00:15
In each suit, there are 13 cards, and of each kind, there are four cards.
00:22
So in this part, in this scenario, a randomly selected card is a black suit or a knight, or a king, sorry.
00:30
So the probability that the card is of a black suit or it's a king.
00:40
This is equal to the probability of it being a black card plus the probability of it being a king minus the probability of it being a black card and a king.
00:50
So there are a total of four suits.
00:53
There are spades, clubs, diamonds, and hearts...
