Problem 1E

An experiment results in one of the following sample points: E1, E2, E3, E4, or E5.

a. Find P(E3) if P(E1) = .1, P(E2) = .2, P(E4) = .1, and P(E5) = .1.

b. Find P(E3) if P(E1) = P(E3), P(E2) = .1, P(E4) = .2, and P(E5) = .1.

c. Find P(E3) if P(E1) = P(E2) = P(E4) = P(E5) = .1.

Step-by-Step Solution:

Step 1 of 3</p>

a) We have to find

Given

We know that the total probability is one

++++=1

                             0.1+0.2++0.1+0.1=1

                                                   0.5+=1

                                                          =1-0.5

                                                                      =0.5

Hence

Step 2 of 3</p>

b)  We have to find

Given

We know that

++++=1

                     +0.1++0.2+0.1=1

                                               0.4+2=1

                                                      2=1-0.4

                                                        =0.6/2

                                                                    =0.3

Hence

Step 3 of 3
