Chapter 3: Q.41 (page 217)

J and K are independent events. P(J|K) = 0.3. Find P(J).

Short Answer

Expert verified

P(J)=0.3as J and K are independent events.

Step by step solution

01

Content Introduction

Two events are deemed independent if knowledge of one event has no effect on the event of the other. Independent events are ones whose occurrence is not contingent on the occurrence of another event.

02

Content Explanation

A and B are said to be independent event, if any of the following condition is true:

1.P(A|B)=P(A)2.P(B|A)=P(B)3.P(AandB)=P(A)脳P(B)

In the question it is given J and K are independent events and P(J|K)=0.3, it satisfies the condition (1), therefore, we can calculate as follow:

P(J)=P(J|K)=0.3

In a bag, there are six red marbles and four green marbles. The red marbles are marked with the numbers 1, 2, 3,4, 5, and 6. The green marbles are marked with the numbers 1, 2, 3, and 4.

鈥� R = a red marble

鈥� G = a green marble

鈥� O = an odd-numbered marble

鈥� The sample space is S = {R1, R2, R3, R4, R5, R6, G1, G2, G3, G4}.

S has ten outcomes. What is P(G AND O)?

Yand Zare independent events.

a. Rewrite the basic Addition Rule P(YORZ)=P(Y)+P(Z)-P(YANDZ)using the information that Y and Z are independent events.

b. Use the rewritten rule to findP(Z) if P(YORZ)=0.71and PY=0.42

Use the following information to answer the next ten exercises. Forty-eight percent of all Californians registered voters prefer life in prison without parole over the death penalty for a person convicted of first degree murder. Among Latino California registered voters, 55%prefer life in prison without parole over the death penalty for a person convicted of first degree murder. 37.6%of all Californians are Latino. In this problem, let: 鈥� C = Californians (registered voters) preferring life in prison without parole over the death penalty for a person convicted of first degree murder. L = Latino Californians. Suppose that one Californian is randomly selected.

Find P(L).
