Question 1049200: I need some help with this question please
A random variable X follows a continuous distribution, which is symmetric to 0. If P(X ≥2)= 0.4, then which of the following statements are true? (There are more than one true statements)
(a) P(X≥-2)=0.6
(b) P(X≤2)=0.4
(c) P(X≥3)≤0.4
(d) P(X≥2)+ P(X<2)=1

The continuous distribution(f) is symmetric about 0 implies that
:
f(a) = f(-a)
