You are given the following discrete probability distribution: xP(x)
12.25
17.65
24.10
You want to find the variance and a student in the class has proposed that you enter the values 12, 17, and 24 in StatCrunch and find the variance of the three numbers. The student gets an answer of 6.0277 2 = 36.33, which is incorrect. Help the student correct his/her incorrect answer and explain why their solution is incorrect.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
