When two cars pass each other, what is the probability that the second letters of their
number-plates are the same? Assume that
number-plates are of the type KA 1602, for
example.
​

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

b

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
