Suppose that we have two events, A and B, with P(A) = 0.40, P(B) = 0.60, and P(A ∩ B) = 0.20. (a) Find P(A | B). (Round your answer to four decimal places.) P(A | B) = (b) Find P(B | A). P(B | A) = (c) Are A and B independent? Why or why not? A and B independent because .

a.) 0.3333

b.) 0.5

c.) A and B are NOT independent

Step-by-step explanation:

We're given P(A) = 0.4, P(B) = 0.6, P(AnB)

a.) From law of probability,

P(A l B) = P(AnB)/P(B)

P (A l B) = 0.2/0.6 = 0.3333

b.) similarly, going by the above law of probability,

P(B l A) = P(BnA)/P(A)

P(B l A) = 0.2/0.4 = 0.5

c.) Two events A and B are said to be independent if mathematically, any of the following conditions are satisfied.

i.) P(A l B) = P(A)

ii.) P(B l A) = P(B)

Since both conditions stated above are not satisfied, that is:

P(A l B) [0.3333] ≠ P(A) [0.4]

P(B l A) [0.5] ≠ P(B) [0.6]

then the two events A and B are NOT Independent

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry
