Question

Two dice are rolled, write the sample space ‘S’ and number of sample points

n(S). Also write events and number of sample points in the event according to

the given condition.

(i) Sum of the digits on upper face is a even number.

(ii) Sum of the digits on the upper face is multiple of 2.

(iii) Sum of the digits on the upper face is 25.

(iv) Digit on the upper face of the second die is less than the

digit on the first die.​

Answer 1

Step-by-step explanation:

2 dice are rolled

s =(1,1). (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

( 4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4 ) (6,5 ) (6,6)

n (s)=36

A= (2,2) (2,6) (2.4) (4,2)(4.4) (4,6) (6,2) (6,4) (6,6)

n (a) = 9

B=(2,2) (2,6) (2.4) (4,2)(4.4) (4,6) (6,2) (6,4) (6,6)

n (b)= 9

C=0

n (c) = 0

D=(3,4) (3,5) (3,6) (4,5) (4,6)(5,6)

n ((d)= 6
