Question 8

A teacher grading statistics homework finds that none of the students has made more than three errors. 14% have made three errors, 25% have made two errors, and 39% have made one error. Create a probability model for the number of errors in students' statistics homework.

a)

X= Number of errors	0	1	2	3	More than 3
P(X=x)	0.22	0.39	0.25	0.14	0

b)

X= Number of errors	1	2	3	More than 3
P(X=x)	0.39	0.25	0.14	0.22

c)

X= Number of errors	0	1	2	3
P(X=x)	0.22	0.39	0.25	0.14

d)

X= Number of errors	1	2	3
P(X=x)	0.39	0.25	0.14

e)

X= Number of errors	1	2	3	More than 3
P(X=x)	0.39	0.25	0.14	0
