Police stopped 527 drivers. Of those stopped, 298 were ticketed. Of those 298, exactly 127 were cited for more than one violation. Estimate the probability that a driver who was stopped got a ticket.
Which way is the correct one?
1/527=.0018 or 1/298=.003
Or am I way off?
Is my question to vague? I am an older college student struggling to do statistics with no algebra background!!
Way off. Probability = ticketed drivers/total = 298/527 = ?
1/527 = P(a particular driver was stopped)
1/298 = P(a particular driver was ticketed)
Thank you!!!!!
To estimate the probability that a driver who was stopped got a ticket, you need to divide the number of drivers who were ticketed by the total number of drivers stopped. In this case, out of the 527 drivers stopped, 298 were ticketed. Therefore, the correct estimate would be:
Probability = Number of ticketed drivers / Total number of drivers stopped
Probability = 298 / 527
Calculating this division, you get approximately 0.565 or 56.5%. So, the correct estimate is that there is a 56.5% chance that a driver who was stopped got a ticket.
The values 1/527 and 1/298 represent the inverse probabilities, which are not what you are looking for in this case.
