To find the probability of the event "X is on KM," we need to determine the ratio of the favorable outcomes to the total number of possible outcomes.
Since point X is chosen at random on JM, we can consider the length of JM as our sample space.
Let's assume the length of JM is represented by L. The length of KM can be represented by a variable K.
The favorable outcomes in this case would be when point X falls on the segment KM.
To find the probability, we need to compare the length of KM to the length of JM.
Therefore, P(X is on KM) = K / L.
