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.
The slope formula is y2-y1 divided by x2- x1 so -8-6=-14 and -1+3=2
-14/2 =-7
