Each machine will work continuously for a constant time per task, as shown in the table, without stopping between consecutive tasks. If the three machines start working on their tasks simultaneously at the beginning of the 8-hour period, how many times during the 8-hour period will all three machines complete a task simultaneously?
Michael, Kim, Glenda, and Ian all own DVDs, and no DVD is owned by two or more of them. Michael owns $$\frac{1}{2}$$ of the number of DVDs that Kim owns. Glenda owns $$\frac{1}{3}$$ of the number of DVDs that Ian owns. If Kim and Ian own the same number of DVDs, what is the ratio of the total number of DVDs that Michael and Glenda own to the total number of DVDs that Kim and lan own?

Container $$Q$$ contains exactly $$120$$ balls and container $$R$$ contains exactly $$6$$ balls. The balls in container $$Q$$ are numbered from $$1$$ to $$120$$, respectively, and the balls in container $$R$$ are numbered from $$1$$ to $$6$$, respectively. A ball is to be chosen at random from each of containers $$Q$$ and $$R$$.

Quantity A

The probability that the number of the ball chosen from container $$Q$$ will be divisible by $$2$$ or $$3$$

Quantity B

The probability that the number of the ball chosen from container $$R$$ will be divisible by $$2$$ or $$3$$
