Which function does the probability distribution graph represent?
A). P(x) = 2x+1 /20 for x = 1, 2, 3, and 4
B). P(x) = 2x+1 /20 for x = 4, 5, 6 and 7
C). P(x) = 2x+1 /20 for x = 2, 4, 6, and 8
D). P(x) = 2x+1 /20 for x = 1, 3, 5, and 7

Which function does the probability distribution graph represent A Px 2x1 20 for x 1 2 3 and 4 B Px 2x1 20 for x 4 5 6 and 7 C Px 2x1 20 for x 2 4 6 and 8 D Px class=

Respuesta :

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

Answer:

Option: A is the correct answer.

   A)   [tex]P(x)=\dfrac{2x+1}{20}[/tex] for [tex]x=1,\ 2,\ 3\ and\ 4[/tex]

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

[tex]P(x)=\dfrac{2x+1}{20}[/tex] for [tex]x=1,\ 2,\ 3\ and\ 4[/tex]
