Answer: 0.500
Step-by-step explanation:
Given : A normal distribution has a mean of 10 and a standard deviation
of 1.
Let x be a random variable that represents numbers .
The probability of selecting a number that is at most 10 will be
As the area occupied by standard normal curve less than equal to 0 = 0.500
So, required probability = 0.500
