A recent study conducted by a health statistics center found that 27​% of households in a certain country had no landline service. This raises concerns about the accuracy of certain​ surveys, as they depend on​ random-digit dialing to households via landlines. Pick five households from this country at random.

a) What is the probability that all five of them have a​ landline?

b) What is the probability that at least one of them does not have a​ landline?

c) What is the probability that at least one of them does have a​ landline?

A national survey found that 45​% of adults ages​ 25-29 had only a cell phone and no landline. Suppose that three 25-29-year-olds are randomly selected.

a) What is the probability that all of these adults have only a cell phone and no​ landline?

b) What is the probability that none of these adults have only a cell phone and no​ landline?

c) What is the probability that at least one of these adults has only a cell phone and no​ landline?

QUESTION 4 ( 8 marks)

A telemarketer is able make a sale on 27% of the phone calls he makes. Assume that he makes 12 calls in an hour. Answer the following questions, assuming a binomial probability distribution:

Required:

1. What is the probability that he will make exactly four sales in the course of an hour? ( 3 marks)
2. What is the probability that he will make at least three sales in the course of an hour? Hint: Use the approach that requires the least calculation work! ( 5 marks)

Suppose 1.6% of the antennas on new Nokia cell phones are defective. For a random sample of 235 antennas, answer the following questions (assume a Poisson probability distribution):

Required:

1. Calculate the mean and standard deviation for the probability distribution of the number of defective antennas in the random sample. ( 2 marks)
2. What is the probability that exactly five of the antennas will be defective? What is the probability that less than three antennas will be defective? ( 4 marks)

(a) An unstable particle with a mass equal to 3.34 ✕ 10⁻²⁷ kg is initially at rest. The particle decays into two fragments that fly off with velocities of 0.977c and −0.851c, respectively. Find the masses of the fragments. (Hint: Conserve both mass–energy and momentum.)

(b) An unstable particle at rest breaks up into two fragments of unequal mass. The mass of the lighter fragment is equal to 4.00 ✕ 10⁻²⁸ kg and that of the heavier fragment is 1.63 ✕ 10⁻²⁷ kg. If the lighter fragment has a speed of 0.893c after the breakup, what is the speed of the heavier fragment?

An arrow strikes the target at the end of a 27-meter-long lane. It lands at an angle of 4 degrees below the horizontal. What is the initial velocity at which the arrow was launched? Assume that the initial velocity toward the target is entirely horizontal and the angel of the arrow in the target is the direction of the final velocity.
