Okay, we have here then basically 52 playing cards as my sample space.
00:06
And the first one, part a, here.
00:10
What chance is there? one card at random is a club or a three.
00:14
So sample space, 52.
00:16
Now, how many clubs are there in the pack? well, there are three, sorry, 13 clubs, 13 clubs, 13 diamonds, 13 spades, 13 parts.
00:28
Now, how many are threes? there are four threes, three of clubs, three of hearts, three of spades, three of diamonds.
00:36
But you don't count the three of clubs twice.
00:40
So what we have then is 13 clubs, so it's a 13 here, plus not four, but three other cards that are three.
00:50
The hearts, the diamonds, the spades.
00:53
So on top then, not 17, which you might think, but 16.
00:56
The 13 clubs plus the three of spades, three of hearts, three of diamonds.
01:03
And that's the answer.
01:06
Next one, part b, a red card or a king? well, red cards, there are, half the cards are red.
01:13
So red is 26...
