The probability of the success will be 0.3826.
<h3>What is binomial distribution?</h3>Bernoulli's trials are those trials which end up randomly either on success (with probability p) or on failures (with probability 1- p = q (say))
The probability that out of n trials, there'd be x successes is given by
We have
n = 8
p = 0.1
q = 1 – 0.1 = 0.9
x = 1
Then we have
P(1) = ⁸C₁ x (0.1)¹ x (0.9)⁷
P(1) = 0.3826

Answer:
Step-by-step explanation:
Given
---- the perimeter of fencing
Required
The maximum area
Let
So, we have:
This gives:
Divide by 2
Make L the subject
The area (A) of the fence is:
Substitute
Open bracket
Differentiate with respect to W
Set to 0
Solve for 2W
Solve for W
Recall that:
So, the maximum area is:
