Question 931644: An insurance company noted that out of every 100 auto accidents in a small city, there are97 claims of major injury. In a random selection of 12 accidents, find the probability that more than 10 had claims of major injury. Find the mean, standard deviation, and variance of number of accidents with major injury
Answer by ewatrrr(24785)   (Show Source):
You can put this solution on YOUR website! p(major injury) = 97/100 = .97, n = 12
...
P(x > 10) = 1 - p(x ≤10) = 1 - normalcdf(12, .97, 10) = 1-.0486 = .9514 0r 95.14%
.....
mean: .97*12
variance: .97*.03*12
standard deviation: √varience
