Probability

Important Terms, NCERT Exercise 15.1, MCQs, Problems

Important terms
1. Randomness: The word has different definitions in different areas. In mathematics, in a sequence of numbers what shall be the next outcome number cannot be determined, we say it is a random sequence.
e.g. consider the sequence,
1, 3, 5, 7, 9, ?
We can easily predict the next number i.e. 11. This sequence has a pattern and it is non-random.

Consider the following sequence,
62,3, 64,78,75,?
Since we cannot predict the next outcome, we may say it is a random sequence.
