Using the probability of independent events, it is found that P(B) = 0.35, which is represented by a dot over 0.35 on the number line.
What is the probability of independent events?
Suppose that two events, A and B, are independent, hence the probability of both happening is given by the multiplication of the probabilities of each happening, that is:
[tex]P(A \cap B) = P(A)P(B)[/tex]
In this problem, we have that the probabilities are:
[tex]P(A) = 0.4, P(A \cap B) = 0.14[/tex]
Hence:
[tex]0.4P(B) = 0.14[/tex]
[tex]P(B) = \frac{0.14}{0.4}[/tex]
P(B) = 0.35.
P(B) = 0.35, which is represented by a dot over 0.35 on the number line.
