Given that X is a binomial random variable, the binomial probability P(X $\geq$ x) is approximated by the area under a normal curve to the right of:
A)x - 0.5.
B)x + 0.5.
C)x - 1.
D)x + 1.

This is due to the continuity correction factor when approximating a binomial distribution with a normal distribution. To find P(X ≥ x) using a normal approximation, you adjust x by subtracting 0.5, effectively shifting the discrete binomial probability to the continuous normal curve.
