Answer:
Step-by-step explanation:
The sides are rectangle is shown in the diagram
The perimeter of the fence will be
Area of the smaller section of the garden
Differentiating with respect to y we get
Equating with zero we get
Double derivative of area
at y = 9 the area is maximum
The sides of the entire garden are and
The maximum area of the natural fertilizer garden is

This is a binomial probability problem
p = 0.35 = chance of picking 1 person who uses smartphones during meeting/class
n = 7 = sample size
k = 4 = target number of people who use their smartphone
Compute nCk = 7C4 using the nCr combination formula
nCr = (n!)/(r!*(n-r)!)
7C4 = (7!)/(4!*(7-4)!)
7C4 = (7*6*5*4!)/(4!*3!)
7C4 = (7*6*5)/(3!)
7C4 = (210)/(6)
7C4 = 35
Use this coefficient to find the binomial probability
B(k) = binomial probability for input k
B(k) = (nCk)*(p^k)*(1-p)^(n-k)
B(4) = (7C4)*(0.35^4)*(1-0.35)^(7-4)
B(4) = 35*(0.35^4)*(0.65)^3
B(4) = 0.144238
So the approximate answer is 0.144238
This value is accurate to 6 decimal places
