Question

Which function does the probability distribution graph represent?

Answer 1

I guess it's A, because when you graph the function each point lines up to it's y :)

Answer 2

Answer:

Option: A is the correct answer.

   A)   $P(x)=\dfrac{2x+1}{20}$ for $x=1,\ 2,\ 3\ and\ 4$

Step-by-step explanation:

We are given a probability distribution graph as:

when x=1   the value of function is:  P(x)=3/20

when x=2   the value of function is : P(x)=5/20

when x=3   then  P(x)=9/20

and when x=4 then the value of function is P(x)=9/20

Hence, the probability function that satisfies these points is:

                                   Option: A

$P(x)=\dfrac{2x+1}{20}$ for $x=1,\ 2,\ 3\ and\ 4$
