Let the random variable X represent the weight of male black bears before they begin hibernation. Research has shown that X can be modeled by a Normal distribution with a mean of 250 pounds and a standard deviation of 50 pounds. What is the probability that a randomly selected male black bear will weigh more than 325 pounds before beginning hibernation?
a
0.0668
b
0.7486
c
0.2514
d
0.8531
e
0.9332
well you see to solve this equation you must take the classes to aquire such intelegence to understand the basiscs of PEMDAS so then you can start on the more advanced stuff such as this
