Suppose that Box I contains 6 red balls and 9 green balls, and Box II contains 8 red balls and 12 green balls. All the balls of Box I and Box II are mixed together and a ball is chosen at random from them. Let $E_1$ be the event that the ball chosen belonged to Box I and let $E_2$ be the event that the ball chosen belonged to Box II. Let $F_1$ be the event that the ball chosen is red and let $F_2$ be the event that the ball chosen is green.

Then which of the following statements is (are) TRUE?

A

The events $E_1$ and $F_1$ are independent

B

The events $E_2$ and $F_2$ are dependent

C

The conditional probability $P(F_1|E_1)$ is equal to the conditional probability $P(F_1|E_2)$

D

The conditional probability $P(F_1|E_1)$ is greater than the conditional probability $P(F_2|E_2)$

Let $\mathbb{R}$ denote the set of all real numbers. Let $f : \mathbb{R} \to \mathbb{R}$ be an arbitrary function and let $g : \mathbb{R} \to \mathbb{R}$ be the function defined by

$$g(x) = x f(x), \quad \text{for all } x \in \mathbb{R}.$$

Then which of the following statements is (are) TRUE?

A

The function $g$ is always continuous at $x = 0$

B

If $f$ is continuous at $x = 0$, then $g$ is differentiable at $x = 0$

C

If $g$ is differentiable at $x = 0$, then $f$ is continuous at $x = 0$

D

If $g$ is differentiable at $x = 0$, then $\lim_\limits{x \to 0} f(x)$ exists
