What is probability?

Probability is a discipline of mathematics concerned with numerical explanations of the likelihood of an event occurring or the truth of a claim. The probability of an occurrence is a number between 0 and 1, with 0 indicating the event's impossibility and 1 indicating certainty.

How to find the probability of finding two consecutive red marbles?

Given we have 2 red marbles, 3 white marbles, 4 green marbles, and 1 blue marble.

Then the total marble is 2+3+4+1 = 8

The probability to find two marbles is 2/8 = 1/4.

Now the total ball is 6.

The probability two red marbles is 2/6 = 1/3.

Selection of the path is [tex]\frac{1}{4} \times \frac{1}{3} =\frac{1}{12}[/tex],
