The probability mass function of a random variable $X$ is given by $P(X = x) = \frac{^5C_x}{2^5}$, for $x = 0, 1, 2, 3, 4, 5$ and $0$ otherwise. Which of the following is correct?

• A
  $P(X \leq 2) = P(X \geq 3)$
• B
  $P(X \leq 2) > P(X \geq 3)$
• C
  $P(X \leq 2) < P(X \geq 3)$
• D
  $P(X \leq 2) = 2P(X \geq 3)$
