First, a little housekeeping!!
1+1+7x2+7y3+3+2x2−y3 needs to be written as <span>1+1+7x^2+7y^3+3+2x^2−y^3. The " ^ " signifies exponentiation and is essential here.
Now combine like terms:
7y^3-y^3 + 7x^2 + 2x^2 + 1 + 1 + 3
You'll get 6y^3 +9x^2 + 5.</span>

Answer:
Average Mean = 1.8
Step-by-step explanation:
Missing:
X:0 1 2 3 4 5 6
P(x): 0.20 0.30 0.20 0.15 0.10 0.05
Computation:
Average Mean [Probability distribution]
∑[P(x) × X]
= 0 x 0.20 + 1 x 0.30 + 2 x 0.20 + 3 x 0.15 + 4 x 0.10 + 5 x 0.05
= 1.8
Average Mean = 1.8
