(a) The probability that two randomly selected 4-year-old male salamanders will live to be 5 years old is (b) The probability that nine randomly selected 4-year-old male salamanders will live to be 5 years old is

Explanation / Answer

P ( 5 ) = probability that he will live to be 5 year old

P( 5) = 0.94492

a) Probability that two randomly selected 4 year ols male salamanders will live to be 5 years old

= P(5)P(5)

= 0.944922

= 0.89287

Therefore 0.89287 is the required probability here.

b) Probability that two randomly selected 4 year ols male salamanders will live to be 5 years old

= 0.944929

= 0.60056

Therefore 0.60056 is the required probability here.
