For a class activity, your group has been assigned the task of generating a quiz question that requires use of the formula for conditional probability to compute p(b | a). your group comes up with the following question "if p(a and b) = 0.40 and p(a) = 0.20, what is the value of p(b | a)? " what is wrong with this question? hint: consider the answer you get when using the correct formula, p(b | a) = p(a and b)/p(a).

P(A and B) is greater than P(A)

P(A and B) should be smaller than P(A).

Step-by-step explanation:

Given :  P(A and B) = 0.40

P(A) = 0.20

Using the given formula of the conditional probability will be

But we know that the probability of any event cannot be more than 1.

Also, the probability of the intersection must be less than the probability of individual event.

Thus , in the given question P(A and B) must be smaller than P(A).

sorry

sorry, but im pretty sure its a now that i look at it

i will with my problems and all the other things that need to   be on by the way
