Answer:
(a) The probability that two randomly selected 5-year-old male horned beetles will live to be 6 years old is 0.06566.
(b) The probability that six randomly selected 5-year-old male horned beetles will live to be 6 years old is 0.000283.
Explanation:
It is given that the probability that a randomly selected 5-year-old male horned beetle will live to be 6 years old is 0.25624.
(a)
We need to find the probability that two randomly selected 5-year-old male horned beetles will live to be 6 years old.

Therefore the probability that two randomly selected 5-year-old male horned beetles will live to be 6 years old is 0.06566.
(b)
We need to find the probability that six randomly selected 5-year-old male horned beetles will live to be 6 years old.

Therefore the probability that six randomly selected 5-year-old male horned beetles will live to be 6 years old is 0.000283.
