Hexagon DEFGHI is translated on the coordinate plane below to create hexagon D'E'F'G'H'I'
 the translation of hexagon DEFGHI to hexagon D'E'F'G'H'I' is represents by the rule
 d. (x, y)→(x + 7, y − 7)
I ---> (-8, 4)→(x + 7, y − 7)
I' →(-8 + 7, 4 − 7) = (-1,-3)

Answer:

0.0087 probability that a freshman non-Statistics major and then a junior Statistics major are chosen at random

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

What is the probability that a freshman non-Statistics major and then a junior Statistics major are chosen at random?

There are 5 freshman non-Statistics majors out of 102 students.

Then, there will be 18 junior statistics majors out of 101 students(1 will have already been chosen). So

$p = \frac{5}{102}*\frac{18}{101} = \frac{5*18}{102*101} = 0.0087$

0.0087 probability that a freshman non-Statistics major and then a junior Statistics major are chosen at random
