Solution

The correct option is D. 16Given,Sample space for rolling a pair of dice = 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) , (adsbygoogle = window.adsbygoogle || []).push({}); (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) }⇒ Total number of outcomes = 36From the sample space, (1,6), (2,5), (3,4), (4,3), (5,2) and (6,1) gives sum of 7.⇒ Number of favourable outcomes = 6Probability of an event, P(E) = number of favourable outcomestotal number of outcomesP ( getting sum 7) =636=16 Therefore, the probability of getting a sum of 7 on rolling a pair of dice is 16.

What is probability of getting a sum of 7 when two dice are thrown?

So, P(sum of 7) = 1/6.

What is the probability of rolling a 7 with 2 dice?

Probability of rolling a certain number or less for two 6-sided dice. ... Two (6-sided) dice roll probability table..

What is the probability of getting 7 on a dice?

probability of occurrence of this event is zero. We know that, A die only has dots or numbers from 1 to 6, i.e., 1,2,3,4,5,6. ∴ The probability of getting number 7 = 0.
