Answer:
0.5676
Step-by-step explanation:
We have been given these informations from this question ,
probability of 4% = 0.04
q = 1 - p = 1 - 0.04 = 0.96
Sample size n = 60
We solve further by Using binomial probability formula,
P(X = x) = (nCx)*px*(1 - p)^n - x
We have:
(60C0)x 0.04⁰x(0.96⁶⁰+(60C1)x0.04¹x(0.96)⁵⁹+(60C2)x0.04²x (0.96)⁵⁸
From this we would get the probability to be = 0.5676
3log54 + 5log50 - 3log2 - 5log2 = log((54^2 x 50^2)/(2^3 x 2^5)) = log((2,916 x 312,500,000)/(8 x 32)) = log 3,559,570,313 = 9.55
The average height of the fence is 2 m; its length is 20π m. So, its 2-sided area is
A = 2*(2 m)*(20π m) = 80π m² ≈ 251 m²
At 1 L/(100 m²), it will take 2.51 L of paint to paint both sides.
