Question -

In a single throw of a die describe the following events:
(i) A = Getting a number less than 7
(ii) B = Getting a number greater than 7
(iii) C = Getting a multiple of 3
(iv) D = Getting a number less than 4
(v) E = Getting an even number greater than 4.
(vi) F = Getting a number not less than 3.
Also, find A ∪ B, A ∩ B, B ∩ C, E ∩ F, D ∩ F and .



Answer -

Given: A dice isthrown once.

Let us find the givenevents, and also find A  B,A ∩ B, B ∩ C, E ∩ F, D ∩ F and

S = {1, 2, 3, 4, 5, 6}

According to thesubparts of the question, we have certain events as:

(i) A = getting anumber below 7

So, the sample spacesfor A are:

A = {1, 2, 3, 4, 5, 6}

(ii) B = Getting anumber greater than 7

So, the sample spacesfor B are:

B = {Փ}

(iii) C = Gettingmultiple of 3

So, the Sample spaceof C is

C = {3, 6}

(iv) D = Getting anumber less than 4

So, the sample spacefor D is

D = {1, 2, 3}

(v) E = Getting aneven number greater than 4.

So, the sample spacefor E is

E = {6}

(vi) F = Getting anumber not less than 3.

So, the sample spacefor F is

F = {3, 4, 5, 6}

Now,

A = {1, 2, 3, 4, 5, 6}and B = {Փ}

A B = {1, 2, 3, 4, 5, 6}

A = {1, 2, 3, 4, 5, 6}and B = {Փ}

A B = {Փ}

B = {Փ} and C = {3, 6}

B C = {Փ}

F = {3, 4, 5, 6} and E= {6}

E F = {6}

E = {6} and D = {1, 2,3}

D F = {3}
