Answer:
A) 0.20
B) 0.06
Step-by-step explanation:
From the question above we have the following information;
30% of the residents of a particular town read the morning paper
Probability (of the residents that read morning paper) = 0.3
25% read the afternoon paper
Probability (of the residents that read afternoon paper) = 0.25
10% read both
Probability (of the residents that read both) = 0.10
A. One resident is randomly selected. What is the probability that this person reads only the morning paper?
Probability( that this person reads only the morning paper) = Probability (of the residents that read morning paper) - Probability (of the residents that read both)
= 0.30 - 0.10
= 0.20
B. Given that a random resident reads the morning paper, what is the probability that this resident also reads the afternoon paper?
Probability( that this resident also reads the afternoon paper) = Probability (of the residents that read morning paper) × Probability (of the residents that read afternoon paper)
= 0.30 × 0.20
= 0.06
