A jar of marbles contains $$4$$ blue, $$5$$ red, $$1$$ green and $$2$$ black marbles. A marble is chosen at random from the jar. After replacing it, a second marble is chosen. Find the probability of choosing a green and then a red marble. 

If $$P(A)= \dfrac{1}{4}$$, $$P(B)= \dfrac{1}{2}$$, $$P(A\cup B)= \dfrac{5}{8}$$ then $$P(A\cap B)$$ is

If one has three dice, what is the probability of getting three $$4's$$?

Three cards are chosen at random with replacement from a standard deck of $$52$$ cards. What is the probability of choosing an ace, a spade and a four? 

A die is thrown. Let 'A' be the event that the number obtained is greater than $$3$$. Let 'B' be the event that the number obtained is less than $$5$$. Then, $$P(A\cup B)$$ is
