Chapter 5: Q 1.2. Intercepts; Symmetry; Graphing Key Equations (page 314)

Find P(E|L) and P(L|E) Which of these conditional probabilities tells you whether this college鈥檚 EPS students tend to earn lower grades than students in liberal arts and social sciences? Explain.

Short Answer

Expert verified

The probability are 0.219 and 0.50

Step by step solution

01

Step 1. Given Information

The table is:

02

Step 2. Concept Used

Formula used: Probability=NumberoffavorableoutcomesTotalpossibleoutcomes

03

Step 3. Calculation

P(E|L) and P(L|E)

are calculated as:

P(E|L)=8002268+800+588=0.219

P(F|L)=800368+432+800=0.50

The probabilities necessary are 0.219and 0.50, respectively. It is necessary to compare these two estimated probabilities in order to arrive at a conclusion.

Most popular questions from this chapter

Government data show that 8% of adults are full-time college students and that 30% of adults are age 55 or older. Since (0.08)(0.30)=0.024, can we conclude that about 2.4% of adults are college students55 or older? Why or why not?

Playing cards Shuffle a standard deck of playing cards and deal one card. Define events J: getting a jack, and R: getting a red card.

(a) Construct a two-way table that describes the sample space in terms of events J and R.

(b) Find P(J) and P(R).

(c) Describe the event 鈥�J and R鈥� in words. Then find P(JandR)

(d) Explain why P(JorR)鈮�P(J)+P(R) Then use the general addition rule to compute P(JorR).

During World War II, the British found that the probability that a bomber is lost through enemy action on a mission over occupied Europe was 0.05 Assuming that missions are independent, find the probability that a bomber returned safely from 20 missions.

Myspace versus Facebook A recent survey suggests that 85% of college students have posted a profile on Facebook, 54%use Myspace regularly, and 42% do both. Suppose we select a college student at random.

(a) Assuming that there are 20 million college students, make a two-way table for this chance process.

(b) Construct a Venn diagram to represent this setting.

(c) Consider the event that the randomly selected college student has posted a profile on at least one of these two sites. Write this event in symbolic form

using the two events of interest that you chose in (b).

(d) Find the probability of the event described in (c).

Explain your method.

Make a two-way table that displays the sample space.
