i hole it helps you!!

Answer 2

Answer:

6/36 (or) 1/6

Step-by-step explanation:

Total number of dice thrown = 2.

Number of possible outcomes is n(S) = 6² = 36.

Let E₁ be the event of getting the sum equal to 7.

E₁ = (3,4),(4,3),(2,5),(5,2),(1,6),(6,1)

n(E₁) = 6.

Therefore, probability of 'getting sum as 7'.

P(E₁) = n(E₁)/n(S)

       = 6/36

       = 1/6.

Therefore, Required probability = 6/36 (or) 1/6.

Hope it helps!
