Question

An experiment can result in to one of the following 5 outcomes E1, E2, E3, E4, and E5 with
probabilities: P(E1)=0.2 P(E2)=0.3 P(E3)=0.15 P(E4)=0.25 P(E5)=0.10
Define the following 3 events: A={E1, E3, E4) B={E2, E3} C={E2, E5}
Find the following probabilities:
P(A)
P(B)
P(A∩B)
P(A∪ B)
P(A∪C)
P(A∩C)
P(A|B)
P(B|A)
P(C|A)
Are A and B mutually exclusive? Are they independent?
Are A and C mutually exclusive? Are they independent?

Expert Solution
Check Mark
Step 1

Probability: If a random experiment results in n mutually exclusive and equally likely outcomes; out of which m are favourable to the event A, then the probability of occurrence of the event A is denoted by P(A) and is given by 
P(A) = mn; 0mn

Given,

P(E1)=0.2,

P(E2)=0.3,

P(E3)=0.15,

P(E4)=0.25,

P(E5)=0.10

The following three events are,

A={E1, E3, E4),

B={E2, E3},

C={E2, E5}
