Step-by-step explanation:
Given:
- Two different dice are tossed together.
To Find:
- Probability of getting a doublet ?
- Probability of getting a sum of 10, of the numbers on the two dice.
Solution: Total outcomes which will come after tossing two different dice :- 36
[ Outcomes are ➘ ]
- (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)
( 1 ) Doublets (D) are
- (1,1) , (2,2) (3,3) (4,4) (5,5) (6,6)
∴ Favourable outcomes of D = 6
➟ P(D) = Favourable outcomes/Total outcomes
P(D) = 6/36
1/6
So , probability of getting a doublet is 1/6.
______________________
( 2 ) Getting a sum (S) of 10
- (4,6) (5,5) (6,4)
∴ Favourable outcomes of S = 3
➟ P(S) = Favourable outcomes/Total outcomes
P(S) = 3/36
1/12
Hence, probability of getting a sum of 10 is 1/12.
