Step 1 :The area under the curve of a normal distribution sums up to 1. Therefore, if the area to the left of x is 0.789, the area to the right of x would be 1 - 0.789.
Step 2 :Similarly, if the area to the right of x is 0.789, the area to the left of x would be 1 - 0.789.
Step 3 :Let's calculate the area to the right of x when the area to the left of x is 0.789.
Step 4 :left_area = 0.789
Step 5 :right_area = 1 - left_area = 1 - 0.789 = 0.211
Step 6 :Final Answer: The area to the right of $x$ is \( \boxed{0.211} \).
