QuestionGetting selected as class secretary is A and having pizza for lunch is B. If these events are independent events, usingP(A) = 0.70, and P(B) = 0.67, what is P(AB)?

Respuesta :

From the question, we have two events that do not affect each other. They seem independent events. The probability of occurring the two events at the same time is given by the formula:

[tex]P(A\cap B)=P(A)\cdot P(B)[/tex]

Then, since we have that P(A) = 0.70 and P(B) = 0.67, then, we have:

[tex]P(A\cap B)=0.70\cdot0.67=0.469[/tex]

Then, P(AB) = 0.469.
