Answer #1

Area under a normal curve respresents the probability or total probability or sum of all probability, which equal to 1

we know that maximum possible probability for any event is equal to 1

So, the area under the normal curve represents the probability.

Center of the normal curve denotes the mean value because the normal curve symmetrical and it has equal proportion or probability on either side of the mean value.

probability or total probability or sum of all probability, these three has same meaning for area under the normal curve.

For standard normal curve, we have mean = 0 and standard deviaton = 1. These conditions are strictly application for standard normal curve.
