Question

Q14.Two dice are thrown simultaneously then the probability of getting sum 9 is

Answer 1

Answer:

1/11

Step-by-step explanation:

Probability = $\frac{No. of favourable outcomes}{Total no. of outcomes}$

Min sum = 2

Max sum = 12

Total no. of outcomes = (12 - 2) + 1

                                     = 10 + 1

                                     = 11

Favourable outcome = 1

Probability = $\frac{1}{11}$  

Answer 2

Possible outcomes = 36
The sum of both faces be 9 they are (3,6) , ( 4,5) , (5,4) , ( 6,3) .
Then the probability = 4/36 = 1/9 .
