Question

The probability that a randomly selected 2-year-old male garter snake will live to be 3 years old is 0.98492. (a) What is the probability that two randomly selected 2-year-old male garter snakes will live to be 3 years old? (b) What is the probability that five randomly selected 2-year-old male garter snakes will live to be (c) What is the probability that at least one of five randomly selected 2-year-old male garter snakes will not live to be 3 years old? Would it be unusual if selected 2-year-old male garter snakes did not live to be 3 years old? years old? t least one of five randomly (a) The probability that two randomly selected 2-year-old male garter snakes will live to be 3 years old is (Round to five decimal places as needed.) (b) The probability that five randomly selected 2-year-old male garter snakes will live to be 3 years old is (Round to five decimal places as needed.) (c) The probability that at least one of five randomly selected 2-year-old male garter snakes will not live to be 3 years old is (Round to five decimal places as needed.) Would it be unusual if at least one of five randomly selected 2-year-old male garter snakes did not live to be 3 years old? V0,05 because the probability of this happening is

Answer 1

The probability that a randomly selected 2 year old garter snake will live upto 3 years is

p=0.98492

a)The probability that 2 randomly selected 2 year old garter snakes will live upto 3 years is

p2 0.984922 0.97007

b)The probability that 5 randomly selected 2 year old garter snakes will live upto 3 years is

ps 0.984925 0.92684

c)The probability that a randomly selected 2 year old garter snake will not live upto 3 years is

p 1-0.98492 0.01508

Use Binomial distribution. The probability that at least one of five randomly selected 2 year old garter snakes will not live upto 3 years is

1 - (1 - p) 0.07316

No. Because the probability of this happening is more than 0.05.
