Question
Suppose a certain type of small data processing firm is so specialized that some have difficulty
making a profit in their first year of operation. The probability density function that characterizes
the proportion Y that make a profit is given by
Sky*(1 – y)³ 0 <x<1
fy(y) = -
elsewhere.
A. What is the value of k that renders the above a valid density function?
B. Find the probability that at most 50% of the firms make a profit in the first year.
C. Find the probability that at least 80% of the firms make a profit in the first year.
