Given:
Uniform distribution of length of classes between 45.0 to 55.0 minutes.
To determine the probability of selecting a class that runs between 51.5 to 51.75 minutes, find the median of the given upper and lower limit first:
45+55/2 = 50
So the highest number of instances is 50-minute class. If the probability of 50 is 0.5, then the probability of length of class between 51.5 to 51.75 minutes is near 0.5, approximately 0.45. <span />
-6/7 < -6.7
i hope this helps
1% of $32K is $320
5% of $32K is $1600
$1600 + $320 = 6%
TOTAL IS $1920
Your 3rd option, or (-6,-3,0,3,6) would be the answer
