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:

Solution

Step 1 of 3

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
