Answer:

Step 1: Set x to 0

$-2(0) + y = 3$

$y = 3$

(0, 3)

Step 2: Set x to 1

$-2(1) + y = 3$

$-2 + y + 2 = 3 + 2$

$y = 5$

(1, 5)

Step 3: Set x to 2

$-2(2) + y = 3$

$-4 + y + 4 = 3 + 4$

$y = 7$

(2, 7)

Step 4: Set x to 3

$-2(3) + y = 3$

$-6 + y + 6 = 3 + 6$

$y = 9$

Oksanka [162]

The total number of sample space in this item is calculated by adding up all the number of students given. That is,

S = 600 + 400 + 300 + 200 = 1500

The probability is calculated with the equation below.

P = n / S

where P is the probability,
n is the number of sophomores, and
S is the total number of students

Substituting,

P = 400 / 1500 = 4/15
