Question

Two balanced dice are rolled. Find the probability that the sum of numbers on two dice

is smaller than 6.​

Answer 1

Step-by-step explanation:

Probability will be 7/36

Total number of outcome =6*6=36

Favourable outcome :-(1,4)(2,3),(3,2),(4,1),(4,6),(5,5),(6,4)

Number of favourable outcome: 7

Probability:-7/36

Answer 2

OUTCOMES =

(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

NOW FROM THESE 36 OUTCOMES, FAVOURABLE OUTCOMES = 10

THEREFORE, PROBABILITY = 10 /36 =5/18
