Yes, I guess you are supposed to make a proof by induction. Making statements based on opinion; back them up with references or personal experience. Trouble understanding conditional probability question. Probability of selecting a yellow ball on the second draw, given that the first ball drawn was green = Conditional of B given A = Condition probability of B given A

By multiplying each side by $Pr(B)$ we get the multiplication principle and our base case for induction: Or, equivalently, by the commutativity of $\cap$ and $\cdot$, a more convenient form for our purposes: Suppose for our induction hypothesis that we know how to expand the intersection of $n$ sets in terms of conditional probabilities in the form $Pr(A_1\cap A_2\cap\cdots \cap A_n) = Pr(A_1)\cdot Pr(A_2|A_1)\cdot Pr(A_3|A_1\cap A_2)\cdots Pr(A_n|A_1\cap A_2\cap\cdots \cap A_{n-1})$. Is there any bound for the joint probability when the conditional probabilities are difficult to calculate? In this case, the probability of occurrence of an event is calculated depending on other conditions is known as conditional probability. Let A and B be the events of drawing a green in the first draw and yellow ball in the second draw respectively. Solution: Required fields are marked *.
25% of the students passed both the tests and 40% of the students passed the maths test. Is there any bound for the joint probability when the conditional probabilities are difficult to calculate? Conditional probability formula gives the measure of the probability of an event given that another event has occurred.
