gun advertise + one mile per hr accuracy 87%...that is .87 probability the gun will detect a speeder...assume 1% chance the gun detects a speeder who is below the limit...suppose 84% drive below the limit
a. prob the gun detct spding & driver spding
The probability will be 0.84
thank you...how did u calculate the problems---plz show work if you don't mind plz....i really appreciate your help
b. prob the gun detects speeding & the driver wasn't speeding
c. prob the driver was speeding below the speed limit
The chance to detect a speeder who is below the limit is 1%
In this case the 84% of the speeder are below the limit
therefore probability of one being detected is 84/100=0.84
Ok thanks....what about part b and c plz
if the driver was not speeding the probability is 84/100=0.84
c. prob the driver was speeding below the speed limit, again here the speed is below thw limit hence probality is still 84/100=0.84
Ok thank you Simon
