Answer:
p (X= 4) = 0.266
Explanation:
Probability of randomly selected baby elk to survive adulthood = 46%
As per binomial setting
p (X= k) = 
Substituting the given values, we get -
p (X= 4) = 
p (X= 4) = 
p (X= 4) = 0.266

Answer:
a. longitudinal
Explanation:
A longitudinal study examines a given group over a long period of time, so collecting data from the same group of 30 people over their lifetime certainly fits that definition. It's more like an evolution study.
A cross-sectional compares different groups at the same point in time. So, it's more like a survey.
A microgenetic is much focused in time, providing multiple data sets in a short time to examine rapid evolution of a subject.
An experimental study design will make interactions and experiments with the study group, while this is not the case here apparently, and experimental is usually for a much shorter period than a generation.
