Traffic checks on a certain section of highway suggest that 85 % of drivers are speeding there. Since 0.85 times 0.85 equals 0.7225, the multiplication rule might suggest that there is approximately a 72 % chance that two vehicles in a row are both speeding. What's wrong with that reasoning?

The given events are not independent, therefore, multiplication rule cannot be applied.

Step-by-step explanation:

The multiplication rule is applicable only when the two events in consideration are independent. in other words, the probability of one event should not have any effect on the probability of the other event.

The multiplication rule is not applicable in the given scenario because these events are not independent. When the two vehicles are racing against each other then both vehicles will always be speeding which makes the probability of one vehicle dependent on the probability of another.

what the question so we can you out

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
