2. Probability with playing cards and a die

Playing cards

A deck of playing cards will have

$52$ cards altogether.

We can sort the

$52$ cards into the four suits, namely, hearts, clubs, diamonds and spades.

Each suit will comprise of

$13$ cards.

$13$ cards in Spades

$+$

$13$ cards in Clubs

$+$

$13$ cards in Hearts

$+$

$13$ cards in Diamond

$=$

$52$ cards

Let us look at a set of diamond cards.

Imagine all

$13$ cards faced down and shuffled together. What do you think the probability would be that we pick

$5$ of diamonds on the first attempt?

There are

$13$ cards altogether and there is only one card to be picked.

So, the probability of

$5$ of diamonds being picked at random

$=$

$\frac{1}{13}$

Die

Die is a common plaything. It has

$6$ faces, and there are numbers from

$1$ to

$6$ engraved on each of the faces.

What do you think the possible outcomes be if a die is rolled once?

The possible outcomes include

$\{$

$1$ ,

$2$ ,

$3$ ,

$4$ ,

$5$ ,

$6$

$\}$ .

What is the probability that the die lands on

$6$ on the first attempt?

There are

$6$ possible outcomes, and there is only

$1$ favourable outcome.

Therefore, the probability of getting a

$6$ on the first attempt

$=$

$\frac{1}{6}$
