What is the probability of getting a sum of 5 in a toss of a pair of dice?

OPtion

1) 4/13
2) 2/36
3) 8/36
4) 4/35
5) 7/36
6) 5/36
7) 1/6
8) 1/9
9) 5/18
10) None of these

Solution

Total number of outcomes= 36
Total Number of positive outcomes = (1,4) (4,1) (2,3) (3,2) = 4

Probability = 4/36 = 1/9

Correct Option: 8 Best Solution (10)

A.P.Singh   8 years AGO

out of 36 possible combinations, 4 favourable combinations are
(1,4)
(4,1)
(2,3)
(3,2).
hence probability = 4/36=1/9

No of out comes =6*6=36
Required outcomes=(1,4),(4,1),(2,3)(32)=4
P(E)=4/36=1/9
Hence my option is 8

4 possibilities out of 36.
(1,4), (2,3), (3,2), (4,1)
So answer is: 4/36 = 1/9

Himanshu Kesharwani   8 years AGO

total sample space=6*6=36
and desired result=(1,4),(2,3),(3,2),(4,1)
therefore there are 4 desired result so,
probability is 4/36=1/9

jyothi chhabria   8 years AGO

total probality is 6^2=36
sum to be 5 is (1,4),(2,3),(3,2),(4,1)
i.e.4 chances out of 36
i.e 4/36=1/9

Ayush Gupta   8 years AGO

total outcomes=6^2=36
possible pairs are=(1,4),(4,1),(2,3),(3,2)
total possible outcome for sum 5=4
probability of getting sum 5=4/36=1/9
therefore 1/9 is correct answer

Amarnath Kumar Upadhyay   8 years AGO

(1, 4),(2,3),(3,2),(4,1)
total no of samples of rolling pair of dice=36
so probability of getting sum of 5 =4/36=1/9 ans

Like? Yes (1) | No (1)  

Haritha Mummidivarapu   8 years AGO

(1,4), (2,3),(3,2),(4,1)==> chances = 4
total no. of probabilities= 6^2 = 36,
so required probability is 4/36 = 1/9

Bupathikavya   8 years AGO

Possibilities (1 4) (4 1) (2 3) (3 2)
No of poss. = 4
No of outcomes = 36
Probability = 4 /36
= 1/9
