What is the probability that a number selected?

Hence, the probability that a number selected is the average of the numbers = 3/10.

Which is prime number?

A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29. Numbers that have more than two factors are called composite numbers.

Which of the following Cannot be the probability of an event?

The probability of an event cannot be - 1.5 because Probability of an event can never be negative. The probability of happening of an event always lies between 0 to 1 (0 and 1 inclusive) i.e 0 ≤ P(E) ≤ 1 . Also in percentage, it lies between 0 % to 100 %(0 and 100 inclusive) .

Is 0 a prime number?
