Hey, so i've been doing a past paper for Edexcel S2 and i came accross this question:
The random variable T has the normal distribution N(25, 5^2).
(c) Find P(T ≤ 18).
I went and did this question but on the mark scheme, no continuity correction was shown and im not sure why
it just did (18 - 25) / 5
Any idea why that may be? or is the mark scheme wrong?
