The probability helps us to know the chances of an event occurring. The probability of event n occurring is 0.3.
<h3>What is Probability?</h3>The probability helps us to know the chances of an event occurring.
We know that for two independent events the probability of the two events occurring simultaneously is written as,
Now, as we know the probability of event m occurring also we know the probability of both events occurring simultaneously, therefore, the probability of event n occurring can be written as,
Hence, the probability of event n occurring is 0.3.

Answer:
Number of points, x, Number of segments, y
x: 2, 3, 4, 5, ... N,. ...
y: 1, 3, 6, 10, ... (N-1)(N)/2, ...
Step-by-step explanation:
Adding Nth point, there are N-1 new segments,
and (sum over {i = 1 to N-1} of i) total segments. As Gauss knew when he was c.10 yo, the sum is (N-1)(N)/2.
