Let S be the sample space.
Then, n(S) = Number of ways of drawing 2 balls out of 7
= ⁷ C₂
=
=21
Let E = Event of drawing 2 balls, none of which is blue.
∴n(E)= Number of ways of drawing 2 balls out of (2 + 3) balls.
= ⁵ C₂
=
= 10
∴ P (E) =

Step-by-step explanation:
−4x+2y=−8
Step 1: Add -2y to both sides.
−4x+2y+−2y=−8+−2y
−4x=−2y−8
Step 2: Divide both sides by -4.
−4x
−4
=
−2y−8
−4
