2. 60 % of the population of a town read either magazine A or magazine
B, and 10% read both.
2.1 If 50% read magazine A, what is the probability that one person,
selected at random, reads magazine B? [3]
2.2 What type of events are A and B? Give a reason for you answer?
[2]
2.3 Draw a venn diagram to illustrate you answer. [3]
Given "P(A\\cup B)=0.6, P(A\\cap B)=0.1"
2.1
Given P(A)=0.5.
Then
"=0.6+0.1-0.5=0.2"
The probability that one person, selected at random, reads magazine B is 0.2.
2.2
Then the events A and B are independent events.
