Answer:

[tex]P(A \: and \: B) = 0.048[/tex]

Step-by-step explanation:

Recall that the probability of event A , given that event B has occurred is given as:

[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}[/tex]

Since P(A|B) = 0.08 and P(A) = 0.40 are not the the two events are not independent.

We substitute the probabilities to get:

[tex]0.08=\frac{P(A\cap B)}{0.60}[/tex]

[tex]P(A\cap B) = 0.08 \times 0.6 = 0.048[/tex]

Therefore

[tex]P(A \: and \: B) = 0.048[/tex]
