Chapter 5: Q. 1 (page 308)

Another commercial If Aaron tunes into his favorite radio station at a

randomly selected time, there is a0.20 probability that a commercial will be playing.

a. Interpret this probability as a long-run relative frequency.

b. If Aaron tunes into this station at 5randomly selected times, will there be exactly one

time when a commercial is playing? Explain your answer.

Short Answer

Expert verified

a) The relative frequency (which is the number of desired results divided by the number of total outcomes) of event A will be a/100

b) the interpretation is that a commercial will be playing roughly 20% of the time he tunes in to his favourite station over a long period of time.

Step by step solution

01

Part (a) Step 1: Given information

We have to interpret this probability as a long-run relative frequency.

02

Part (a) Step 2: Explanation

The relative frequency (which is the number of desired results divided by the number of total outcomes) of event A will be a/100 across a large number of experiments if the probability of outcome A is a percent.

03

Part (b) Step 1: Given information

We have to tell that will there be exactly one time when a commercial is playing.

04

Part (b) Step 2: Explanation

When dials in to his preferred station, there is a 0.2chance that he will hear an advertisement.

As a result, the interpretation is that a commercial will be playing roughly 20%of the time he tunes in to his favourite station over a long period of time.

Is this your card? A standard deck of playing cards (with jokers removed) consists of 52cards in four suits鈥攃lubs, diamonds, hearts, and spades. Each suit has 13cards, with denominations ace, 2,3,4,5,6,7,8,9,10,jack, queen, and king. The jacks, queens, and kings are referred to as 鈥渇ace cards.鈥� Imagine that we shuffle the deck thoroughly and deal one card. Define events F: getting a face card and H: getting a heart. The two-way table summarizes the sample space for this chance process

b. Find P(HcandF). Interpret this value in context.

c. Find P(HcorF).

Suppose that a student is randomly selected from a large high school. The probability

that the student is a senior is 0.22. The probability that the student has a driver鈥檚 license

is 0.30. If the probability that the student is a senior or has a driver鈥檚 license is 0.36,

what is the probability that the student is a senior and has a driver鈥檚 license?
