Answer:
a ) 0.9
<em>Expected number of bower-birds that have bowers featuring reflective decor</em>
<em> μ = 0.9</em>
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given Sample size 'n' = 20
Given data A population consists of twenty bower-birds, six of which have bowers featuring reflective decor.
<em>probability of success </em>
![p = \frac{x}{n} = \frac{6}{20} =0.3](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7Bx%7D%7Bn%7D%20%3D%20%5Cfrac%7B6%7D%7B20%7D%20%3D0.3)
Given three of the bower-birds are randomly sampled with replacement from this population.
So we will choose sample size 'n'= 3
Let 'X' be the random variable in binomial distribution
Expected number of bower-birds that have bowers featuring reflective decor
<em> μ = n p</em>
= 3 × 0.3
=0.9
<u><em>conclusion:-</em></u>
<em>Expected number of bower-birds that have bowers featuring reflective decor</em>
<em> μ = 0.9</em>
