I thought the question seemed odd.
I think the question should be:
Assume that X has a normal distribution, and find the indicated probability.
The mean is µ= 15.2 and the standard deviation is σ = 0.9.
Find the probability that X is greater than 16.1.

Maybe the question was right. Variations on this question seem common on US exam papers.
Here's the same Q that Tamooma asked
59) The mean is μ = 15.2 and the standard deviation is σ = 0.9.
Find the probability that X is greater than 15.2.
A) 0.5000 B) 1.0000 C) 0.9998 D) 0.0003
The answer was indeed A} 0.5
