A student goes to the library. Let events π΅ = the student checks out a book and π· = the student checks out a DVD. Suppose that π(π΅)=0.40, π(π·)=0.30 and π(π΅ AND π·)=0.20. a. Find π(π΅|π·). b. Find π(π·|π΅). c. Are π΅ and π· independent? d. Are π΅ and π· mutually exclusive?
Added by Sule B.
Step 1
We are given π(π΅ AND π·) = 0.20 and π(π·) = 0.30. Plugging these values into the formula, we get: π(π΅|π·) = 0.20 / 0.30 = 2/3 So, π(π΅|π·) = $\boxed{\frac{2}{3}}$. b. Show moreβ¦
