What is The area under the normal curve to the right of mu and mu equals?

In a standard normal distribution, the area under the curve to the right of the mean (mu) is 0.5. This is because the normal distribution is symmetric around the mean, and half of the total area (which equals 1) lies to the right of the mean and half to the left. Therefore, for any normal distribution where mu is the mean, the area to the right of mu is always 0.5.
