Answer: C) There is a probability that the outcome is within 1 standard deviation of the mean.
Step-by-step explanation:
The Standard Deviation Rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean. According to the rule,
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations
Therefore, the correct answer is
C) There is a probability that the outcome is within 1 standard deviation of the mean.
The 87 degree angle is a supplementary angle, and the corresponding angle (BAC) is 93 degrees. I know this because two supplementary angles add up to 180 degrees. 180 degrees - 87 degrees = 93 degrees. :D
