Answer:
Its D
Step-by-step explanation:
Solution :
It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :
1.
2.
Now consider,
⇒
⇒
⇒
⇒
= 0.2
Therefore, the value of T is 0.2
Thus, option (c) is correct.
Since this is an absolute value equation, it will have two answers. For the first answer, take away the absolute value bars and solve 3x + 1 = 2. Subtract 1 from both sides to get 3x = 1 and divide each side by 3 to get x = 1/3. Now onto the second solution. This time, take away the absolute value bars and make the other side of the equation, the 2, negative, to get 3x + 1 = -2. Now solve this by subtracting 1 from each side to get 3x = -3 and divide each side to get the other answer which is x = -1. The answer is x = -1 or 1/3, hope this helps!
