Answer:
The expected number of bowerbirds in the sample that will have bower featuring reflective color is E(X)=0.9
Step-by-step explanation:
We can model this with a binomial random variable, with sample size n=3 and probability of success p=0.3.
[tex]p=X/n=6/20=0.3[/tex]
The expected number of bowerbirds in the sample that will have bower featuring reflective color can be calculated as:
[tex]E(X)=np=3\cdot 0.3=0.9[/tex]
