Chapter 5: Q. T5.3 (page 357)

Which one of the following is true about the events “Owner has a Chevy” and

“Owner’s truck has four-wheel drive”?

a. These two events are mutually exclusive and independent.

b. These two events are mutually exclusive, but not independent.

c. These two events are not mutually exclusive, but they are independent.

d. These two events are neither mutually exclusive nor independent.

e. These two events are mutually exclusive, but we do not have enough information to determine if they are independent.

Short Answer

Expert verified

The correct option is :

c. These two events are not mutually exclusive, but they are independent.

Step by step solution

01

Given information

We have to tell about the events “Owner has a Chevy” and“Owner’s truck has four-wheel drive".

02

Explanation

We know that

  • A total of 125truck owners were asked what type of truck they had and if it had four-wheel drive.
  • The likelihood of the person owning a Dodge or having a four-wheel drive is high.
  • As there are thirty two drivers that own Chevy four-wheel and all 125own four-wheel which implies that events occur at the same time.

Therefore, the given event is not mutually exclusive but independent i.e. option (c) is correct option.

Lucky penny? Harris Interactive reported that 33%of U.S. adults believe that

finding and picking up a penny is good luck. Assuming that responses from different

individuals are independent, what is the probability of randomly selecting 10U.S. adults

and finding at least 1person who believes that finding and picking up a penny is good

luck?

Color-blind men About 7% of men in the United States have some form of red-green color blindness. Suppose we randomly select one U.S. adult male at a time until we find one who is red-green color-blind. Should we be surprised if it takes us 20 or more men? Describe how you would carry out a simulation to estimate the probability that we would have to randomly select 20 or more U.S. adult males to find one who is red-green color blind. Do not perform the simulation.

Temperature and hatching How is the hatching of water python eggs influenced by the temperature of a snake’s nest? Researchers randomly assigned newly laid eggs to one of three water temperatures: cold, neutral, or hot. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother.

Suppose we select one of the eggs at random.

a. Given that the chosen egg was assigned to hot water, what is the probability that it hatched?

b. If the chosen egg hatched, what is the probability that it was not assigned to hot water?

Roulette An American roulette wheel has 38 slots with numbers 1through36,0,and 00, as shown in the figure. Of the numbered slots, 18are red, 18are black, and 2—the 0and 00—are green. When the wheel is spun, a metal ball is dropped onto the middle of the wheel. If the wheel is balanced, the ball is equally likely to settle in any of the numbered slots. Imagine spinning a fair wheel once. Define events B: ball lands in a black slot, and E: ball lands in an even-numbered slot. (Treat0and 00as even numbers.)

a. Make a two-way table that displays the sample space in terms of events Band E.

b. Find P(B)andP(E).

c. Describe the event “Band E” in words. Then find the probability of this event.

d. Explain why P(BorE)≠P(B)+P(E). Then use the general addition rule to compute P(BorE).
