Answer:
i think its A
Step-by-step explanation:
The solution set is 
Explanation:
The given equation is 
To determine the solution set of the equation, let us solve the equation.
Adding both sides of the equation by 3, we have,

Taking square root on both sides of the equation, we get,


Thus, the solution of the equation is 
The solution set of the equation is the set which contains all the solutions of the equations.
Thus, writing the solutions of the equation using set notation, we have,

Thus, the solution set is 
Answer:
1//12.
Step-by-step explanation:
The possible ways to get a sum of 4 are (1, 3), (3, 1), (2, 2) .
There are a total of 6 * 6 = 36 possible outcomes when 2 dice are rolled.
Thus the probability of the sum being 4 = 3 / 36 = 1/12 (answer).
