First of,
or, in probability is subtraction and not means you shouldn't use green (therefore leaving you with yellow and red)

When 10 by anything you just write the amount of 0 so if it was 10^12 i would write 12 0s so 10^6 1,000,000
Answer:
A
Step-by-step explanation:
Given the 2 equations
y = 3x + 3 → (1)
y = - 2x + 3 → (2)
Substitute y = 3x + 3 into (2)
3x + 3 = - 2x + 3 ( add 2x to both sides )
5x + 3 = 3 ( subtract 3 from both sides )
5x = 0 , then
x = 0
Substitute x = 0 into (1)
y = 3(0) + 3 = 0 + 3 = 3
solution is (0, 3 ) → A
